The best way to do this would be via the 'procmail' mail filtering
program -- a lot of Linux dists already come with procmail installed &
running, you just need to set up rules in /etc/procmailrc or
~user/.procmailrc (look for lines in /etc/sendmail.cf like:

Mprocmail,      P=/usr/bin/procmail, F=DFMSPhnu9, S=11/31, R=21/31,
T=DNS/RFC822/X-Unix,
                A=procmail -Y -m $h $f $u
Mlocal,         P=/usr/bin/procmail, F=lsDFMAw5:/|@qSPfhn9, S=10/30,
R=20/40,
                A=procmail -Y -a $h -d $u
)

Otherwise, the install is a little tricky (especially if you're not to
familiar w/ sendmail) but well worthwhile.  Procmail should work on pretty
much any UNIX system running sendmail or a similar SMTP-compatible MTA.
