>(mail delivery agent) such as /bin/mail or /usr/local/bin/procmail.
>(I do, but have it forwarded to Hotmail for convenience.)

>Make sure your shell account host has procmail available
>for use (do a "which procmail" at a shell prompt).
>If available:
>
>1.) Create directory ~/.procmail:
> % mkdir ~/.procmail
>
>2.) Create file ~/.procmailrc with these contents
>(modify with actual user values):
>
>PATH=/bin:/usr/bin:/usr/local/bin:/home/<username>/bin # example path
>PMDIR=$HOME/.procmail # literal directory name: location of filter
>rules and log file
>MAILDIR=$HOME/mail # example directory: filtered mail spooled here
>DEFAULT=$HOME/inbox # example default mailspool: could be
>/var/mail/<username> on some systems
>LOGFILE=$PMDIR/procmail.log # you'll want this for debugging
>VERBOSE=off
>SHELL=/bin/sh
>INCLUDERC=$PMDIR/rc.devnull # name of your procmail recipe file
>COMSAT=off
>
>3.) In directory ~/.procmail, create your procmail recipes
>file (in this case "rc.devnull"), with contents like this
>(the exact example here being merely theoretical):
>
># save mail filtered on the "From" line match to $MAILDIR/russellwhitaker,
># for future amusement, or evidence.

>* ^From:.*russellwhitaker@hotmail.com
>russellwhitaker
>
>or
>
># simply discard mail from example destination
>:0
>* ^From:.*russellwhitaker@hotmail.com
>/dev/null
>
>4.) Create or modify your ~/.forward file to contain:
>
><username>, # usually, your local username
>"|IFS=' '&&exec /usr/local/bin/procmail -f-||exit 75 #<username>"
>
>"/usr/local/bin/procmail" is a typical location; use the value of
>"which procmail" above or "/usr/bin/env procmail" if your
>system supports it.

>Some enlightened sysadmins actually have procmail
>set up as the local MDA, in which case step #4 above is
>unnecessary.

>At least one emotionally unbalanced person on this list
>has threatened to change email addresses if list members
>don't listen to his rants. That's OK. Once he shows
>up and engages in similar rants, it's easy to add recipe lines
>to ~/.procmail/rc.devnull. It takes much less effort to
>add the recipe than it does for that person to change email
>addresses. Let him waste time trying.
