Actually I might have misunderstood what you meant because of your mention
to "custom" passwd.
You can already authenticate users in your master.passwd file. All you
have to do is to add "enable auth" to a listener:
listen on em0 tls certificate "my.crt" enable auth
listen on em0 smtps certificate "my.crt" enable auth
It will only work if you configured the listener to support tls or smtps
as authentication is only allowed over a secure channel.
What is not yet possible is to use alternate authentication sources.
