Oh, for sure, Sendmail's an amazing piece of software and can be munged to
do all kinds of weird and wonderful things.  During the time I ran Roaring
Penguin, we ran into quite a few situations where Sendmail's flexibility
saved the day.

But still... it's showing its age, and Postfix is a really nice tool also.
Not quite as flexible as Sendmail, but close, and much more straightforward.

I wouldn't have a clue how to do that. :)  I'm still a Postfix newbie.

Well, it turned out to be super-easy.  The only minor wrinkle was that
I made the mimedefang socket an inet socket (127.0.0.1:8443) because Postfix
runs in a chroot environment, so it was just easier that way.
Then I just added this to /etc/postfix/master.cf:

smtpd_milters = inet:127.0.0.1:8443

and everything just worked!

Despite having used Sendmail for a long time (20 years?), I have to say I'm
a fan of Postfix.  Very easy to set up and quite well designed.

Regards,

Dianne.
