It's not a matter of functionality, it's a matter of architecture.

All that you name (ezmlm, imap, pop3d) are things external to Qmail, they
don't touch the core distribution, you can strip them out and Qmail will
work... All Qmail can be summed up in the following:

- qmail-queue/clean (the queue)
- qmail-lspawn/local (delivery agent, local)
- qmail-rspawn/remote (delivery agent, remote via SMTP)
- qmail-inject (injector, local)
- qmail-smtpd (injector, remote via SMTP)

And with this I'm already including a number of things not "required" to run
qmail, just usual stuff you see in the distribution and you're going to use.
 
And note that those 8 binaries are completely independent in regard to their
application space and security model.

Qmail is _designed_ to be a set of different little tools running in
different processes with different users, relying on the OS for security,
Notes/Exchange/iPlanet follow another model... In my dialect "FASO TOTO ME",
meaning, "I take care of the whole kit and kaboodle"...

James does that, it's design is absolutely orthogonal to Qmail and Postfix.
Ok, it's "customizable" like Qmail (you can create pipelines more or less
like you do w/ Qmail) but it ain't the same thing architecturally.

On one thing we agree... Notes is a piece of crap... Let's stop talking
about it because it gets on my nerves big times...
