Postix avoids content-filtering forwarded mail that is forwarded
inside Postfix.
To force Milter inspection, resubmit the message.
frank-list: "|/usr/sbin/sendmail -f owner-frank-l...@example.com
frank-list-out@localhost
owner-frank-list: y...@example.com
frank-list-out: :include:/lists/frank-list
and block direct mail to frank-list-out on the SMTP port, if you're
concerned about abuse.
This is a crude example; if you need more control over the message
use a list manager such as mailman.
