No more ugly and kludgy than default_mail_env.

All that's needed is something to mangle logins. In fact the logic would 
be very similar to default_mail_env.

We don't use SQL database to store users and moving to such would incur 
great time and effort (and require major reworking of all our mail 
system). So it's a non-option.

Like I said, other pop3 servers like teapop have explicit support for 
this. It would be nice if we could move to dovecot without loss of 
functionality.
