Vpopmail: http://inter7.com/vpopmail.html
should be able to do what you want, it supports usernames like
'user at domain'. It's designed to work with the qmail MTA, but the website
explains how to make it work with postfix. It's in the ports under
mail/vpopmail-stable.

SMTP will obviously be handled by sendmail/postfix. Since courier-imap
is listed as compatible with vpopmail, I assume you can use it for POP3
and IMAP. The only disadvantage is that vpopmail is designed to work
with qmail, so it uses the same tools and syntax (tcpserver,
/var/qmail/control).

For ASMTP, look under SASL on http://www.postfix.org/docs.html.

I assume this can be done with sendmail too, but I'm not sure whether
sendmail works with vpopmail.
