I just want to let you know what i am doing about mail,
maybe it's helpful:
1) I am using 'getmail' for my users which
can't redirect their old addresses.
Seems to operate rock solid so far.
2) Currently i run exim as MTA, but everyone is on its own here.
Maybe sendmail has some extensions to do this POP before SMTP thing...
(which i have turned off on my site, it's just ugly)
I like exim for its clear yet powerful configuration.
coupled with my postgres i have a central for user/pass and alias entries.
IMAP server (courier-imap here) looks up in the postgres, too.
5) grey (or even the new hype: green) listing is a desperate attempt
to block spam. I'll never use that.
btw: My box provides an email platform for custom domains (free and easy)
PUBBOX Postmaster + spam-killer. Free email addresses at http://pubbox.net/
