eBox includes everything you mentioned, plus users in LDAP and a web
GUI for user management. (But eBox is something of a beast... If you
can configure your setup by hand, it's a much leaner solution.) Google:
"ubuntu ebox".
eBox comes with eGroupWare for webmail, but my favorite webmail is
Roundcube. I've been using Roundcube to an eBox server for over a year now.
Personally, I much prefer Maildir to mbox. eBox by default will use
mbox for "virtual" mail users, but I've configured it to use Maildir for
local user accounts instead.
Finally, check out a program called "imapsync". It makes it easy to
migrate email from one system to another, as long as they both speak IMAP.

It took me 16 years to get away from Slackware and now I need to move
away from sendmail , qpopper, and SquirrelMail. The plan is to use
postfix, dovecot (POP and IMAP) and something_for_webmail. Currently
sendmail is set to use mbox format and postfix and dovecot will
happily go along with that (I'd rather not have to convert all of the
users' mail spool to maildir format). Is openwebmail a reasonable
choice (2008 was last update)? We were using SquirrelMail. We'll
also be tacking on spamassasin and clamav unless there's compelling
reasons not to (we're using them now with sendmail just fine).
Thanks in advance for your thoughts (and prayers :) ).
