Well .. What password/user databases do you use? One way is to set
default_realm and set the @domain for all users in passdb/userdb.

Another way is to patch the code. Below is a patch for plaintext
authentication.

Or maybe I should make option that if given realm is default_realm, it
would look up the user without the realm. I'm not sure if it's worth
doing though.

BTW. Your mail to dovecot-list got stuck at spamassassin. I raised the
spam points a bit and lowered HTML mail's points a bit. Better would be
if I could update SA's whitelist automatically when people subscribe.
But I'm not really sure how to do that with mailman.
