15.3.1.5. Processing Incoming E-Mail with procmail
This step is completely optional. The above described sendmail configuration calls procmail for each received email, but you could have called procmail using the .forward file (see the procmail man page). Procmail is a handy tool to block spam and to sort incoming email.
You need to setup a .procmailrc file to use procmail . See the man page for procmail, procmailrc, and procmailex (examples). My setup demonstrates, how to ignore certain email messages and split email-collections (digest) into pieces:
# -- mail filtering -- procmail is called by sendmail --
PATH=/bin:/usr/bin
MAILDIR=$HOME/Mail
LOGFILE=$MAILDIR/from
# keep in mind:
# use ":0:" when writing to a file
# use ":0" when writing to a device, e.g. /dev/null, or send email
# - make a backup of *all* incoming mail, but ignore mail tagged below -
:0 c:
*! ^Sissa-Repro
backup
# - keep only last 50 messages
:0 ic
| cd backup && rm -f dummy 'ls -t msg.* | sed -e 1,50d'
# - delete email coming through the 'postdocs' email list, when
# it is not of any interest

# Split mailing list from the sissa preprint server into individual emails
# - this is quite complicated :( I can flip through the list much
# faster and ignore preprints which have uninteresting titles. Instead of
# having to browse through the whole list, my mailer will just present a
# list of papers.
# 1. split it in individual messages
:0
* ^From no-reply@xxx.lanl.gov
| formail +1 -de -A "Sissa-Repro: true" -s procmail
# 2. reformat messages a bit
# 2.1. extract 'Title:' from email-Body and add to email-header
as 'Subject:'
:0 b
* ^Sissa-Repro
*! ^Subject
TITLE=| formail -xTitle:
:0 a
|formail -A "Subject: $TITLE " -s procmail
# 2.2. store in my incoming sissa-email folder. Here, we could
# also reject (and thereafter delete) uninteresting 'Subjects'
# we could also mark more interesting subjects as urgend or send a copy
# to regular mail box.

By the way, there is a tk GUI tool to configure procmail (I think it is called dotfiles ).
