# Hack to work around the fact that sendmail will not execute a 
# pipeline containing multiple commands connected together.
#
# This script calls demime (http://scifi.squawk.com/demime.html), a Perl 
# script to rip out all mime types embedded within an e-mail, then pass
# the stripped e-mail along to majordomo.  The arguments to resend come from
# the command invoked from sendmail, as configured in the /etc/aliases file.
#
# Demime first, then approve then majordomo. Demime allows approved
# to trigger off of the mime header for inserting the approved header.
# When approved fails, a non-zero exit status is returned.  In that case,
# nothing is even sent to resend.
#
# Comment out this line if you already have DEMIME configured, and have a
# demime_junkmail.cf file configured in your environment.
