I disagree. I've been through docs/RFCs/etc and I have yet to see it's
purpose. As far as I can tell, it's just sendmail listening on another
port.

The pertinent line in /etc/mail/sendmail.cf:

0 DaemonPortOptions=Port=587, Name=MSA, M=E

and I've commented it out. If someone can tell me how I'm supposed to
talk to it, I'd be interested - otherwise I see it just as an immature
default. And, if it's setup for MUAs, why does it listen on all IPs?
Just localhost, no?

Thanks,

Hans
