$HOME/.procmailrc examples

       For a description of the rcfile format see procmailrc(5).

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

       This man page shows several example recipes.  For examples of  complete
       rcfiles  you can check the NOTES section in procmail(1), or look at the
       example rcfiles in /usr/share/doc/procmail/examples.

       Sort out all mail coming from the  scuba-dive  mailing  list  into  the
       mailfolder scubafile (uses the locallockfile scubafile.lock).

              * ^TOscuba

       Forward all mail from peter about compilers to william (and keep a copy
       of it here in petcompil).

              * ^From.*peter
              * ^Subject:.*compilers
                 :0 c


       An equivalent solution that accomplishes the same:

              :0 c
              * ^From.*peter
              * ^Subject:.*compilers

                 :0 A

       An equivalent, but slightly slower solution that accomplishes the same:

              :0 c
              * ^From.*peter
              * ^Subject:.*compilers


              :0 ic
              | cd backup && rm -f dummy `ls -t msg.* | sed -e 1,32d`

       If  your system doesn't generate or generates incorrect leading `From '
       lines on every mail, you can fix this by calling up procmail  with  the
       -f- option.  To fix the same problem by different means, you could have
       inserted the following two recipes above  all  other  recipes  in  your
       rcfile.   They will filter the header of any mail through formail which
       will strip any leading `From ', and automatically regenerates it subse-

              :0 fhw
              | formail -I "From " -a "From "

       Add the headers of all messages that didn't come from the postmaster to
       your private header collection (for statistics or mail debugging);  and
       use  the  lockfile `headc.lock'.  In order to make sure the lockfile is
       not removed until the pipe has finished, you  have  to  specify  option
       `w';  otherwise  the  lockfile would be removed as soon as the pipe has
       accepted the mail.

              :0 hwc:
              * !^FROM_MAILER
              | uncompress headc.Z; cat >>headc; compress headc

       Or, if you would use the more efficient gzip instead of compress:

              :0 hwc:
              * !^FROM_MAILER
              | gzip >>headc.gz

       Forward all mails shorter than 1000 bytes to my home address (no  lock-
       file needed on this recipe).

              * < 1000
              ! myname@home

       Split  up  incoming  digests  from  the surfing mailing list into their
       individual messages, and store them into surfing, using surfing.lock as
       the locallockfile.

              * ^Subject:.*surfing.*Digest
              | formail +1 -ds >>surfing

       Store  everything  coming  from  the  postmaster or mailer-daemon (like
       bounced mail) into the file postm, using postm.lock as  the  locallock-

              * ^FROM_MAILER

       conventions, this might not be enough).

              :0 h c
              * !^FROM_DAEMON
              * !^X-Loop: your@own.mail.address
              | (formail -r -I"Precedence: junk" \
                  -A"X-Loop: your@own.mail.address" ; \
                 echo "Mail received.") | $SENDMAIL -t

       A  more  complicated  autoreply  recipe  that implements the functional
       equivalent of the well known vacation(1) program.  This recipe is based
       on  the  same  principles as the last one (prevent `ringing' mail).  In
       addition to that however, it maintains a vacation database by  extract-
       ing  the name of the sender and inserting it in the vacation.cache file
       if the name was new (the vacation.cache file is maintained  by  formail
       which will make sure that it always contains the most recent names, the
       size of the file is limited to a maximum of approximately 8192  bytes).
       If the name was new, an autoreply will be sent.

       As  you  can  see, the following recipe has comments between the condi-
       tions.  This is allowed.  Do not put comments on the  same  line  as  a
       condition though.

              SHELL=/bin/sh    # for other shells, this might need adjustment

              :0 Whc: vacation.lock
               # Perform a quick check to see if the mail was addressed to us
              * $^To:.*\<$\LOGNAME\>
               # Don't reply to daemons and mailinglists
              * !^FROM_DAEMON
               # Mail loops are evil
              * !^X-Loop: your@own.mail.address
              | formail -rD 8192 vacation.cache

                :0 ehc         # if the name was not in the cache
                | (formail -rI"Precedence: junk" \
                     -A"X-Loop: your@own.mail.address" ; \
                   echo "I received your mail,"; \
                   echo "but I won't be back until Monday."; \
                   echo "-- "; cat $HOME/.signature \
                  ) | $SENDMAIL -oi -t

       Store  all  messages concerning TeX in separate, unique filenames, in a
       directory named texmail (this directory has to exist); there is no need
       to use lockfiles in this case, so we won't.

              * (^TO|^Subject:.*)TeX[^t]

       The  same as above, except now we store the mails in numbered files (MH
       mail folder).


       Store  all  the messages about meetings in a folder that is in a direc-
       tory that changes every month.  E.g.  if  it  were  January  1994,  the
       folder  would have the name `94-01/meeting' and the locallockfile would
       be `94-01/meeting.lock'.

              * meeting
              `date +%y-%m`/meeting

       The same as above, but, if the `94-01' directory wouldn't have existed,
       it is created automatically:

              MONTHFOLDER=`date +%y-%m`

              :0 Wic
              * ? test ! -d $MONTHFOLDER
              | mkdir $MONTHFOLDER

              * meeting

       The same as above, but now by slightly different means:

              MONTHFOLDER=`date +%y-%m`
              DUMMY=`test -d $MONTHFOLDER || mkdir $MONTHFOLDER`

              * meeting

       If  you are subscribed to several mailinglists and people cross-post to
       some of them, you usually receive several  duplicate  mails  (one  from
       every  list).   The following simple recipe eliminates duplicate mails.
       It tells formail to keep an 8KB cache file in which it will  store  the
       Message-IDs  of  the most recent mails you received.  Since Message-IDs
       are guaranteed to be unique for every new mail, they are ideally suited
       to  weed  out  duplicate mails.  Simply put the following recipe at the
       top of your rcfile, and no duplicate mail will get past it.

              :0 Wh: msgid.lock
              | formail -D 8192 msgid.cache

       Beware if you have delivery problems in  recipes  below  this  one  and
       procmail  tries  to  requeue the mail, then on the next queue run, this
       mail will be considered a duplicate and will be thrown away.  For those
       not quite so confident in their own scripting capabilities, you can use
       the following recipe instead.  It puts duplicates in a separate  folder
       instead  of  throwing them away.  It is up to you to periodically empty
       the folder of course.

              :0 Whc: msgid.lock
              | formail -D 8192 msgid.cache

       `show'  or `mark' or some other MH program is running.  This problem is
       expected to be fixed in some future version  of  MH,  but  until  then,
       you'll  have  to  balance the risk of lost or corrupt sequences against
       the benefits of the unseen sequence.

       When delivering to emacs folders  (i.e.,  mailfolders  managed  by  any
       emacs  mail package, e.g., RMAIL or VM) directly, you should use emacs-
       compatible lockfiles.  The emacs mailers are a bit braindamaged in that
       respect,  they  get very upset if someone delivers to mailfolders which
       they already have in their  internal  buffers.   The  following  recipe
       assumes that $HOME equals /home/john.


              * ^Subject:.*whatever

       Alternatively,  you can have procmail deliver into its own set of mail-
       boxes, which you then periodically empty and copy over  to  your  emacs
       files  using  movemail.  Movemail uses mailbox.lock local lockfiles per
       mailbox.  This actually is the preferred mode of operation in  conjunc-
       tion with procmail.

       To  extract  certain  headers from a mail and put them into environment
       variables you can use any of the following constructs:

              SUBJECT=`formail -xSubject:`    # regular field
              FROM=`formail -rt -xTo:`        # special case

              :0 h                            # alternate method
              KEYWORDS=| formail -xKeywords:

       If you are using temporary files in a procmailrc file, and want to make
       sure  that  they  are removed just before procmail exits, you could use
       something along the lines of:

              TRAP="/bin/rm -f $TEMPORARY"

       The TRAP keyword can also be used to change the exitcode  of  procmail.
       I.e.  if  you want procmail to return an exitcode of `1' instead of its
       regular exitcodes, you could use:

              TRAP="exit 1;"   # The trailing semi-colon is important
                               # since exit is not a standalone program

       Or, if the exitcode does not need to depend on the  programs  run  from
       the TRAP, you can use a mere:
       first condition matches only if it is found in the header.  The  second
       condition only matches at the start of the body.

              :0 b
              * ^From[ :].*print-server
              * B ?? ^^%!
              | lpr

       The same as above, but now by slightly different means:

              * ^From[ :].*print-server
                :0 B b
                * ^^%!
                | lpr


              :0 HB b
              * ^^(.+$)*From[ :].*print-server
              * ^^(.+$)*^%!
              | lpr

       Suppose  you  have  two  accounts, you use both accounts regularly, but
       they are in very distinct places (i.e., you can  only  read  mail  that
       arrived at either one of the accounts).  You would like to forward mail
       arriving at account one to account two, and the other way around.   The
       first  thing  that comes to mind is using .forward files at both sites;
       this won't work of course, since you will  be  creating  a  mail  loop.
       This  mail  loop  can  be  avoided by inserting the following recipe in
       front of all other recipes  in  the  $HOME/.procmailrc  files  on  both
       sites.   If  you  make sure that you add the same X-Loop: field at both
       sites, mail can now safely be  forwarded  to  the  other  account  from
       either of them.

              :0 c
              * !^X-Loop: yourname@your.main.mail.address
              | formail -A "X-Loop: yourname@your.main.mail.address" | \
                 $SENDMAIL -oi yourname@the.other.account

       If  someone  sends  you a mail with the word `retrieve' in the subject,
       the following will automatically send back the contents of info_file to
       the  sender.   Like in all recipes where we send mail, we watch out for
       mail loops.

              * !^From +YOUR_USERNAME
              * !^Subject:.*Re:
              * !^FROM_DAEMON
              * ^Subject:.*retrieve
              | (formail -r ; cat info_file) | $SENDMAIL -oi -t

              * ^Subject: send file [0-9a-z]
              * !^X-Loop: yourname@your.main.mail.address
              * !^Subject:.*Re:
              * !^FROM_DAEMON
              * !^Subject: send file .*[/.]\.
                MAILDIR=$HOME/fileserver # chdir to the fileserver directory

                :0 fhw                   # reverse mailheader and extract name
                * ^Subject: send file \/[^ ]*
                | formail -rA "X-Loop: yourname@your.main.mail.address"

                FILE="$MATCH"            # the requested filename

                :0 ah

       The  following example preconverts all plain-text mail arriving in cer-
       tain encoded MIME formats into a more compact 8-bit format which can be
       used and displayed more easily by most programs.  The mimencode(1) pro-
       gram is part of Nathaniel Borenstein's metamail package.

              * ^Content-Type: *text/plain
                :0 fbw
                * ^Content-Transfer-Encoding: *quoted-printable
                | mimencode -u -q

                   :0 Afhw
                   | formail -I "Content-Transfer-Encoding: 8bit"

                :0 fbw
                * ^Content-Transfer-Encoding: *base64
                | mimencode -u -b

                   :0 Afhw
                   | formail -I "Content-Transfer-Encoding: 8bit"

       The following one is rather exotic, but it only serves to demonstrate a
       feature.   Suppose  you  have  a  file  in  your  HOME directory called
       ".urgent", and the (one) person named in that file is the sender of  an
       incoming  mail,  you'd  like  that mail to be stored in $MAILDIR/urgent
       instead of in any of the normal mailfolders it would have  been  sorted
       in.   Then  this  is  what  you  could  do  (beware,  the filelength of
       $HOME/.urgent should be well below $LINEBUF, increase LINEBUF if neces-

              URGMATCH=`cat $HOME/.urgent`

              * $^From.*${URGMATCH}

       =0xff= should be substituted with the real 8-bit characters):

              DEFAULT=|     # pipe to stdout instead of
                            # delivering mail as usual
