NAME
       procmail - autonomous mail processor

SYNOPSIS
       procmail [-ptoY] [-f fromwhom]
	    [parameter=value | rcfile] ...
       procmail [-toY] [-f fromwhom] [-a argument] ...
	    -d recipient ...
       procmail [-ptY] -m [parameter=value] ...  rcfile
	    [argument] ...
       procmail -v

DESCRIPTION
       For a quick start, see NOTES at the end.

       Procmail  should be invoked automatically over the .forward file mecha
       nism as soon as mail arrives.  Alternatively, when installed by a  sys
       tem  administrator,  it	can  be invoked from within the mailer immedi
       ately.  When invoked, it  first	sets  some  environment  variables  to
       default	values,  reads the mail message from stdin until an EOF, sepa
       rates the body from the header, and then, if no command line  arguments
       are  present,  it  starts  to  look for a file named $HOME/.procmailrc.
       According to the processing recipes in this file, the mail message that
       just  arrived gets distributed into the right folder (and more).  If no
       rcfile is found, or processing of the rcfile falls off the  end,  proc
       mail will store the mail in the default system mailbox.

       If  no rcfiles and no -p have been specified on the command line, proc
       mail will, prior to reading $HOME/.procmailrc, interpret commands  from
       /etc/procmailrc	(if  present).	 Care  must  be  taken	when  creating
       /etc/procmailrc, because, if circumstances permit, it will be  executed
       with  root  privileges  (contrary  to  the  $HOME/.procmailrc  file  of
       course).

       If running suid root or with root privileges, procmail will be able  to
       perform	as a functionally enhanced, backwards compatible mail delivery
       agent.

       Procmail can also be used as a general purpose mail filter, i.e.,  pro
       visions	have  been  made to enable procmail to be invoked in a special
       sendmail rule.

       The rcfile format is described in detail in the procmailrc(5) man page.

       The  weighted  scoring  technique  is  described in detail in the proc
       mailsc(5) man page.

       Examples for rcfile recipes can be looked up in the  procmailex(5)  man
       page.

   Signals
       TERMINATE   Terminate prematurely and requeue the mail.

       HANGUP	   Terminate prematurely and bounce the mail.

       INTERRUPT   Terminate prematurely and bounce the mail.

       QUIT	   Terminate prematurely and silently lose the mail.

       ALARM	   Force a timeout (see TIMEOUT).

       USR1	   Equivalent to a VERBOSE=off.

       USR2	   Equivalent to a VERBOSE=on.

OPTIONS
       -v   Procmail  will  print its version number, display its compile time
	    configuration and exit.

       -p   Preserve any old environment.  Normally procmail clears the  envi
	    ronment upon startup, except for the value of TZ.  However, in any
	    case: any default values will override any preexisting environment
	    variables, i.e., procmail will not pay any attention to any prede
	    fined environment variables, it will happily overwrite  them  with
	    its  own  defaults.   For  the  list of environment variables that
	    procmail will preset see the procmailrc(5) man page.  If  both  -p
	    and  -m  are  specified,  the list of preset environment variables
	    shrinks to just: LOGNAME, HOME, SHELL, ORGMAIL and MAILDIR.

       -t   Make procmail fail softly, i.e., if procmail  cannot  deliver  the
	    mail  to  any  of  the  destinations  you  gave, the mail will not
	    bounce, but will  return  to  the  mailqueue.   Another  delivery-
	    attempt will be made at some time in the future.

       -f fromwhom
	    Causes  procmail  to  regenerate  the  leading  From   line with
	    fromwhom as the sender (instead of -f one could use the  alternate
	    and  obsolete  -r).   If fromwhom consists merely of a single -,
	    then procmail will only update the timestamp on the From	line
	    (if present, if not, it will generate a new one).

       -o   Instead of allowing anyone to generate From  lines, simply over
	    ride the fakes.

       -Y   Assume traditional Berkeley mailbox format,  ignore  any  Content-
	    Length: fields.

       -a argument
	    This  will	set  $1  to  be equal to argument.  Each succeeding -a
	    argument will set the next number variable ($2, $3, etc).  It  can
	    be used to pass meta information along to procmail.  This is typi
	    cally done by passing along the $@x information from the  sendmail
	    mailer rule.

       -d recipient ...
	    This  turns  on  explicit  delivery  mode, delivery will be to the
	    local user recipient.  This, of course, only is possible if  proc
	    mail  has  root privileges (or if procmail is already running with
	    the recipients euid and  egid).   Procmail	will  setuid  to  the
	    intended recipients and delivers the mail as if it were invoked by
	    the recipient with no arguments (i.e.,  if	no  rcfile  is	found,
	    delivery is like ordinary mail).  This option is incompatible with
	    -p.

       -m   Turns procmail into a general purpose mail filter.	In  this  mode
	    one  rcfile  must  be  specified  on  the command line.  After the
	    rcfile, procmail will accept an unlimited number of arguments.  If
	    the  rcfile  is  an  absolute path starting with /etc/procmailrcs/
	    without backward references (i.e. the parent directory  cannot  be
	    mentioned)	procmail  will,  only  if  no  security violations are
	    found, take on the identity of the owner of the  rcfile  (or  sym
	    bolic  link).   For  some advanced usage of this option you should
	    look in the EXAMPLES section below.

ARGUMENTS
       Any arguments containing an = are considered to be environment  vari
       able  assignments,  they will all be evaluated after the default values
       have been assigned and before the first rcfile is opened.

       Any other arguments are presumed to be rcfile paths  (either  absolute,
       or if they start with ./ relative to the current directory; any other
       relative path is relative to $HOME,  unless  the  -m  option  has  been
       given,  in  which  case	all relative paths are relative to the current
       directory); procmail will start with the first one it finds on the com
       mand  line.   The  following  ones will only be parsed if the preceding
       ones have a not matching HOST-directive entry, or in case  they	should
       not exist.

       If  no  rcfiles	are specified, it looks for $HOME/.procmailrc.	If not
       even that can be found,	processing  will  continue  according  to  the
       default settings of the environment variables and the ones specified on
       the command line.

EXAMPLES
       Examples for rcfile recipes can be looked up in the  procmailex(5)  man
       page.  A small sample rcfile can be found in the NOTES section below.

       Skip the rest of this EXAMPLES section unless you are a system adminis
       trator who is vaguely familiar with sendmail.cf syntax.

       The -m option is typically used when procmail is called from  within  a
       rule  in  the  sendmail.cf  file.  In order to be able to do this it is
       convenient to create an extra procmail  mailer  in  your  sendmail.cf
       file  (in  addition  to the perhaps already present local mailer that
       starts up procmail).  To create such a procmail	mailer	Id  suggest
       something like:

	      Mprocmail, P=/usr/bin/procmail, F=mSDFMhun, S=11, R=21,
		      A=procmail -m $h $g $u

       This  enables you to use rules like the following (most likely in rule
       set 0) to filter mail through the  procmail  mailer  (please  note  the
       leading	tab  to  continue  the	rule, and the tab to separate the com
       ments):

	      R$*<@some.where>$*
		      $#procmail $@/etc/procmailrcs/some.rc $:$1@some.where.procmail$2
	      R$*<@$*.procmail>$*
		      $1<@$2>$3       Already filtered, map back

       And /etc/procmailrcs/some.rc could be as simple as:

	      SENDER = "<$1>"		      # fix for empty sender addresses
	      SHIFT = 1 		      # remove it from $@

	      :0			      # sink all junk mail
	      * ^Subject:.*junk
	      /dev/null

	      :0 w			      # pass along all other mail
	      ! -oi -f "$SENDER" "$@"

       Do watch out when sending mail from within the /etc/procmailrcs/some.rc
       file,  if  you send mail to addresses which match the first rule again,
       you could be creating an endless mail loop.

DIAGNOSTICS
       Autoforwarding mailbox found
			      The system mailbox had its suid or sgid bit set,
			      procmail terminates with EX_NOUSER assuming that
			      this mailbox must not be delivered to.

       Bad substitution of "x"
			      Not a valid environment variable name specified.

       Closing brace unexpected
			      There  was no corresponding opening brace (nest
			      ing block).

       Conflicting options    Not all option combinations are useful

       Conflicting x suppressed
			      Flag x is not compatible with some other flag on
			      this recipe.

       Couldnt create "x"    The   system   mailbox  was  missing  and	could
			      not/will not be created.

       Couldnt create maildir part "x"
			      The maildir folder "x" is missing  one  or  more
			      required	subdirectories	and procmail could not
			      create them.

       Couldnt create or rename temp file "x"
			      An error occurred in the mechanics of   deliver
			      ing to the directory folder "x".

       Couldnt determine implicit lockfile from "x"
			      There  were no >> redirectors to be found, us
			      ing simply $LOCKEXT as locallockfile.

       Couldnt read "x"      Procmail was unable to open an rcfile or it  was
			      not a regular file, or procmail couldnt open an
			      MH directory to find the highest numbered  file.

       Couldnt unlock "x"    Lockfile  was  already gone, or write permission
			      to the directory where the lockfile is has  been
			      denied.

       Deadlock attempted on "x"
			      The  locallockfile  specified  on this recipe is
			      equal to a still active $LOCKFILE.

       Denying special privileges for "x"
			      Procmail will not  take  on  the	identity  that
			      comes  with the rcfile because a security viola
			      tion was found (e.g.  -p or variable assignments
			      on  the  command	line) or procmail had insuffi
			      cient privileges to do so.

       Descriptor "x" was not open
			      As procmail was started, stdin, stdout or stderr
			      was  not	connected (possibly an attempt to sub
			      vert security)

       Enforcing stricter permissions on "x"
			      The system mailbox of the recipient was found to
			      be unsecured, procmail secured it.

       Error while writing to "x"
			      Nonexistent  subdirectory,  no write permission,
			      pipe died or disk full.

       Exceeded LINEBUF       Buffer overflow detected, LINEBUF was too small,
			      PROCMAIL_OVERFLOW has been set.

       MAILDIR is not an absolute path

       MAILDIR path too long

       ORGMAIL is not an absolute path

       ORGMAIL path too long

       default rcfile is not an absolute path

       default rcfile path too long
			      The  specified  items full path, when expanded,
			      was longer than LINEBUF or didnt start  with  a
			      file separator.

       Excessive output quenched from "x"
			      The  program  or filter "x" tried to produce too
			      much output for the current  LINEBUF,  the  rest
			      was  discarded  and  PROCMAIL_OVERFLOW  has been
			      set.

       Extraneous x ignored   The action line or other flags  on  this	recipe
			      makes flag x meaningless.

       Failed forking "x"     Process  table  is full (and NORESRETRY has been
			      exhausted).

       Failed to execute "x"  Program not in path, or not executable.

       Forced unlock denied on "x"
			      No write permission in the directory where lock
			      file "x" resides, or more than one procmail try
			      ing to force a lock at exactly the same time.

       Forcing lock on "x"    Lockfile "x" is going to be removed by force be
			      cause of a timeout (see also: LOCKTIMEOUT).

       Incomplete recipe      The start of a recipe was found, but it stranded
			      in an EOF.

       Insufficient privileges
			      Procmail either needs root privileges,  or  must
			      have  the  right (e)uid and (e)gid to run in de
			      livery mode.  The mail will bounce.

       Invalid regexp "x"     The regular expression "x" contains errors (most
			      likely some missing or extraneous parens).

       Kernel-lock failed     While trying to use the kernel-supported locking
			      calls, one of them failed (usually indicates  an
			      OS  error), procmail ignores this error and pro
			      ceeds.

       Kernel-unlock failed   See above.

       Lock failure on "x"    Can only occur if you specify  some  real  weird
			      (and  illegal)  lockfilenames or if the lockfile
			      could not be  created  because  of  insufficient
			      permissions or nonexistent subdirectories.

       Lost "x" 	      Procmail	tried  to  clone  itself but could not
			      find back rcfile "x" (it either got  removed  or
			      it was a relative path and you changed directory
			      since procmail opened it last time).

       Missing action	      The current recipe was found to be incomplete.

       Missing closing brace  A nesting block was started, but never finished.

       Missing name	      The -f option needs an extra argument.

       Missing argument       You specified the -a option but forgot the argu
			      ment.

       Missing rcfile	      You specified the -m  option,  procmail  expects
			      the name of an rcfile as argument.

       Missing recipient      You  specified  the -d option or called procmail
			      under a different name, it expects one  or  more
			      recipients as arguments.

       No space left to finish writing "x"
			      The  filesystem  containing  "x"	does  not have
			      enough free space to permit delivery of the mes
			      sage to the file.

       Out of memory	      The  system is out of swap space (and NORESRETRY
			      has been exhausted).

       Processing continued   The unrecognised options on the command line are
			      ignored, proceeding as usual.

       Program failure (nnn) of "x"
			      Program  that  was  started by procmail returned
			      nnn instead of EXIT_SUCCESS (=0); if nnn is neg
			      ative,  then this is the signal the program died
			      on.

       Quota exceeded while writing "x"
			      The filesize quota  for  the  recipient  on  the
			      filesystem containing "x" does not permit deliv
			      ering the message to the file.

       Renaming bogus "x" into "x"
			      The system mailbox of the recipient was found to
			      be bogus, procmail performed evasive actions.

       Rescue of unfiltered data succeeded/failed
			      A filter returned unsuccessfully, procmail tried
			      to get back the original text.

       Skipped: "x"	      Couldnt do anything  with  "x"  in  the  rcfile
			      (syntax error), ignoring it.

       Suspicious rcfile "x"  The owner of the rcfile was not the recipient or
			      root, the file was world writable, or the direc
			      tory  that  contained  it was world writable, or
			      this was the default rcfile  ($HOME/.procmailrc)
			      and either it was group writable or the directo
			      ry that contained it was group writable (the rc
			      file was not used).

       Terminating prematurely whilst waiting for ...
			      Procmail	received a signal while it was waiting
			      for ...

       Timeout, terminating "x"
			      Timeout has occurred on program or filter "x".

       Timeout, was waiting for "x"
			      Timeout has occurred on program, filter or  file
			      "x".   If  it  was  a program or filter, then it
			      didnt seem to be running anymore.

       Truncated file to former size
			      The file could not be delivered to successfully,
			      so the file was truncated to its former size.

       Truncating "x" and retrying lock
			      "x"  does not seem to be a valid filename or the
			      file is not empty.

       Unable to treat as directory "x"
			      Either the suffix on "x" would indicate that  it
			      should  be  an  MH  or maildir folder, or it was
			      listed as an second folder into which  to  link,
			      but it already exists and is not a directory.

       Unexpected EOL	      Missing  closing quote, or trying to escape EOF.

       Unknown user "x"       The specified recipient does not have  a	corre
			      sponding uid.

EXTENDED DIAGNOSTICS
       Extended  diagnostics can be turned on and off through setting the VER
       BOSE variable.

       [pid] time & date      Procmails pid and a timestamp.  Generated when
			      ever  procmail  logs a diagnostic and at least a
			      second has elapsed since the last timestamp.

       Acquiring kernel-lock  Procmail now tries to kernel-lock the  most  re
			      cently opened file (descriptor).

       Assigning "x"	      Environment variable assignment.

       Assuming identity of the recipient, VERBOSE=off
			      Dropping	all  privileges  (if  any), implicitly
			      turns off extended diagnostics.

       Bypassed locking "x"   The mail spool directory was not	accessible  to
			      procmail, it relied solely on kernel locks.

       Executing "x"	      Starting program "x".  If it is started by proc
			      mail directly (without an  intermediate  shell),
			      procmail	will show where it separated the argu
			      ments by inserting commas.

       HOST mismatched "x"    This host was called "x", HOST  contained  some
			      thing else.

       Locking "x"	      Creating lockfile "x".

       Linking to "x"	      Creating a hardlink between directory folders.

       Match on "x"	      Condition matched.

       Matched "x"	      Assigned "x" to MATCH.

       No match on "x"	      Condition didnt match, recipe skipped.

       Non-zero exitcode (nnn) by "x"
			      Program that was started by procmail as a condi
			      tion or as the action of a recipe with  the  W
			      flag  returned nnn instead of EXIT_SUCCESS (=0);
			      the usage indicates that this is not an entirely
			      unexpected condition.

       Notified comsat: "$LOGNAME@offset:file"
			      Sent  comsat/biff a notice that mail arrived for
			      user $LOGNAME at offset in file.

       Opening "x"	      Opening file "x" for appending.

       Rcfile: "x"	      Rcfile changed to "x".

       Reiterating kernel-lock
			      While attempting several locking methods, one of
			      these  failed.   Procmail  will  reiterate until
			      they all succeed in rapid succession.

       Score: added newtotal "x"
			      This condition scored added points, which  re
			      sulted in a newtotal score.

       Unlocking "x"	      Removing lockfile "x" again.

WARNINGS
       You  should create a shell script that uses lockfile(1) before invoking
       your mail shell on any mailbox file other than the system mailbox  (un
       less of course, your mail shell uses the same lockfiles (local or glob
       al) you specified in your rcfile).

       In the unlikely event that you absolutely need to kill procmail	before
       it  has finished, first try and use the regular kill command (i.e., not
       kill -9, see the subsection Signals for	suggestions),  otherwise  some
       lockfiles might not get removed.

       Beware  when  using  the -t option, if procmail repeatedly is unable to
       deliver the mail  (e.g.,  due  to  an  incorrect  rcfile),  the	system
       mailqueue  could fill up.  This could aggravate both the local postmas
       ter and other users.

       The /etc/procmailrc file might be executed with root privileges, so  be
       very careful of what you put in it.  SHELL will be equal to that of the
       current recipient, so if procmail has to invoke the shell, youd better
       set it to some safe value first.  See also: DROPPRIVS.

       Keep  in  mind that if chown(1) is permitted on files in /etc/procmail
       rcs/, that they can be chowned to root (or anyone else) by  their  cur
       rent  owners.   For  maximum security, make sure this directory is exe
       cutable to root only.

       Procmail is not the proper tool for  sharing  one  mailbox  among  many
       users,  such  as when you have one POP account for all mail to your do
       main. It can be done if you manage to configure your MTA  to  add  some
       headers	with the envelope recipient data in order to tell Procmail who
       a message is for, but this is usually not the right thing to do.   Per
       haps  you want to investigate if your MTA offers virtual user tables,
       or check out the multidrop facility of Fetchmail.

BUGS
       After removing a lockfile by force, procmail waits $SUSPEND seconds be
       fore  creating  a  new lockfile so that another process that decides to
       remove the stale lockfile will not remove the  newly  created  lock  by
       mistake.

       Procmail  uses  the  regular  TERMINATE signal to terminate any runaway
       filter, but it does not check if the filter responds to that signal and
       it only sends it to the filter itself, not to any of the filters chil
       dren.

       A continued Content-Length: field is not handled correctly.

       The embedded newlines in a continued  header  should  be  skipped  when
       matching instead of being treated as a single space as they are now.

MISCELLANEOUS
       If there is an existing Content-Length: field in the header of the mail
       and the -Y option is not specified, procmail will trim the field to re
       port the correct size.  Procmail does not change the fieldwidth.

       If  there  is no Content-Length: field or the -Y option has been speci
       fied and procmail appends to regular mailfolders, any lines in the body
       of the message that look like postmarks are prepended with > (disarms
       bogus mailheaders).  The regular expression that is used to search  for
       these postmarks is:
	      \nFrom

       If  the	destination  name  used  in  explicit  delivery mode is not in
       /etc/passwd, procmail will proceed as if explicit delivery mode was not
       in  effect.   If not in explicit delivery mode and should the uid proc
       mail is running under, have no corresponding  /etc/passwd  entry,  then
       HOME  will  default  to /, LOGNAME will default to #uid, SHELL will de
       fault to /bin/sh, and ORGMAIL will default to /tmp/dead.letter.

       When in explicit delivery mode, procmail will generate a leading  From
	 line  if  none  is present.  If one is already present procmail will
       leave it intact.  If procmail is not invoked with one of the  following
       user  or  group	ids :  root,  daemon, uucp, mail, x400, network, list,
       slist, lists or news, but still has to generate or accept a new From
       line,  it will generate an additional >From  line to help distinguish
       fake mails.

       For security reasons procmail will only use an absolute or  $HOME-rela
       tive  rcfile  if  it  is  owned	by  the  recipient  or root, not world
       writable, and the directory it is contained in is not  world  writable.
       The  $HOME/.procmailrc  file has the additional constraint of not being
       group-writable or in a group-writable directory.

       If /var/mail/$LOGNAME is a bogus mailbox (i.e., does not belong to  the
       recipient,  is unwritable, is a symbolic link or is a hard link), proc
       mail will upon startup try to rename it into a file starting with  BO
       GUS.$LOGNAME. and ending in an inode-sequence-code.  If this turns out
       to be impossible, ORGMAIL will have no initial value,  and  hence  will
       inhibit delivery without a proper rcfile.

       If /var/mail/$LOGNAME already is a valid mailbox, but has got too loose
       permissions on it, procmail will correct  this.	 To  prevent  procmail
       from doing this make sure the u+x bit is set.

       When  delivering  to  directories,  MH folders, or maildir folders, you
       dont need to use lockfiles to  prevent  several	concurrently  running
       procmail programs from messing up.

       Delivering  to MH folders is slightly more time consuming than deliver
       ing to normal directories or mailboxes, because procmail has to	search
       for  the  next available number (instead of having the filename immedi
       ately available).

       On general failure procmail will return EX_CANTCREAT, unless option  -t
       is specified, in which case it will return EX_TEMPFAIL.

       To  make  egrepping of headers more consistent, procmail concatenates
       all continued header fields; but only internally.  When delivering  the
       mail, line breaks will appear as before.

       If  procmail is called under a name not starting with procmail (e.g.,
       if it is linked to another name and invoked as such), it  comes	up  in
       explicit  delivery  mode,  and expects the recipients names as command
       line arguments (as if -d had been specified).

       Comsat/biff notifications are done using udp.  They are sent  off  once
       when  procmail  generates  the regular logfile entry.  The notification
       messages have the following extended format (or as close as you can get
       when final delivery was not to a file):
	      $LOGNAME@offset_of_message_in_mailbox:absolute_path_to_mailbox

       Whenever  procmail  itself  opens a file to deliver to, it consistently
       uses the following kernel locking strategies: fcntl(2).

       Procmail is NFS-resistant and eight-bit clean.

NOTES
       Calling up procmail with the -h or -? options will cause it to  display
       a command-line help and recipe flag quick-reference page.

       There exists an excellent newbie FAQ about mailfilters (and procmail in
       particular); it is maintained by Nancy McGough  and  can
       be obtained by sending a mail to mail-server@rtfm.mit.edu with the fol
       lowing in the body:
	      send usenet/news.answers/mail/filtering-faq

       If procmail is not installed globally  as  the  default	mail  delivery
       agent  (ask your system administrator), you have to make sure it is in
       voked when your mail arrives.  In this case  your  $HOME/.forward  (be
       ware,  it has to be world readable) file should contain the line below.
       Be sure to include the single and double quotes, and  unless  you  know
       your  site to be running smrsh (the SendMail Restricted SHell), it must
       be an absolute path.

       "|exec /usr/bin/procmail"

       Some mailers (notably exim) do not currently accept the	above  syntax.
       In such case use this instead:

       |/usr/bin/procmail

       Procmail  can  also  be invoked to postprocess an already filled system
       mailbox.  This can be useful if you  dont  want	to  or	cant  use  a
       $HOME/.forward  file (in which case the following script could periodi
       cally be called from within cron(1),  or  whenever  you	start  reading
       mail):

	      #!/bin/sh

	      ORGMAIL=/var/mail/$LOGNAME

	      if cd $HOME &&
	       test -s $ORGMAIL &&
	       lockfile -r0 -l1024 .newmail.lock 2>/dev/null
	      then
		trap "rm -f .newmail.lock" 1 2 3 13 15
		umask 077
		lockfile -l1024 -ml
		cat $ORGMAIL >>.newmail &&
		 cat /dev/null >$ORGMAIL
		lockfile -mu
		formail -s procmail <.newmail &&
		 rm -f .newmail
		rm -f .newmail.lock
	      fi
	      exit 0


   A sample small $HOME/.procmailrc:
       PATH=/usr/local/bin:/usr/bin:/bin
       MAILDIR=$HOME/Mail      #youd better make sure it exists
       DEFAULT=$MAILDIR/mbox   #completely optional
       LOGFILE=$MAILDIR/from   #recommended

       :0:
       * ^From.*berg
       from_me

       :0
       * ^Subject:.*Flame
       /dev/null

       Other examples for rcfile recipes can be looked up in the procmailex(5)
       man page.
