Okay. Postfix certainly doesn't support milter, though the equivalent can be
done other ways. There have been noises about writing a milter-compatible
extension to Postfix, but AFAIK no one's scratched that itch b/c so far it's
just been easier to do things Postfix-style instead....

Assuming I'm following how you're doing this, yes.

Postfix can do uucp.

Not that are as usable and any more secure. SSH alternatives that are open 
source are worse than OpenSSH. Other web servers don't support all the 
modules Apache does....

Yes. The fact that it's been scrutinized for 25 years now and people are
still unearthing remote remote exploits when they examine it certainly does
say something about its design and coding style. I'm not certain that's the 
point you were trying to make, though ;-)
