====== procmail ======

===== Information =====

Setup procmail to handle mail filtering.

===== Installation =====

<code bash>
# cd /usr/ports/mail/procmail
# make install clean
</code>


===== Configuration =====

==== Sendmail ====

First we have to rebuild ''sendmail'''s cf file to include procmail.

''/usr/src/contrib/sendmail/cf/README'' has some notes on that.


  - Copy ''/usr/src/etc/sendmail/freebsd.mc'' to a new filename:\\ <code># cd /usr/src/etc/sendmail
# cp freebsd.mc custom.mc
</code>
  - Edit ''custom.mc'' - we need to add the following:\\ <code diff>

  - Build your ''custom.mc'' (or in my case, ''shalom.mc'') file:\\ <code># m4 -D_CF_DIR_=/usr/src/etc/sendmail/../../contrib/sendmail/cf/   /usr/src/etc/sendmail/../../contrib/sendmail/cf/m4/cf.m4 shalom.mc > shalom.cf</code>
  - Copy the new sendmail cf file into place (and also copy the mc file):\\ <code># cp custom.* /etc/mail/</code>
  - Backup the current cf file:\\ <code># cd /etc/mail
# cp sendmail.cf sendmail.cf.orig
</code>
  - Copy your new cf into place:\\ <code># cp custom.cf sendmail.cf</code>
  - Restart Sendmail:\\ <code># /etc/rc.d/sendmail restart</code>


==== Procmail ====

Setup a default global procmail file (''/usr/local/etc/procmailrc''):

<code>
# Please check if all the paths in PATH are reachable, remove the ones that
# are not.

PATH=$HOME/bin:/usr/bin:/usr/ucb:/bin:/usr/local/bin:.
MAILDIR=$HOME/mail      # You'd better make sure it exists
DEFAULT=/var/mail/$LOGNAME
LOGFILE=$MAILDIR/log.file
VERBOSE=yes
LOCKFILE=$HOME/.lockmail



# Anything that has not been delivered by now will go to $DEFAULT
# using LOCKFILE=$DEFAULT$LOCKEXT
</code>

Eventually this file will have spam filtering options configured (after I setup [[spamassassin]])

===== Notes =====

  ================================================================ ===============
  If you are a system administrator you should consider integrating procmail
  into the mail-delivery system -- for advanced functionality, speed AND
  SECURITY --.  For more information about this topic you should look in the
  examples/advanced file.
  ================================================================ ===============
  If you would like to inspect the results before running make install:
  All installable files can be found in the new/ subdirectory.
