yes and infact jzawone@two gets delivered to jzawone
not ideal at all in that respect
however in my case thats ok
the _real_ usernames are sort of secret at least they are never given
out publically
and it means that the login for smtp auth or imap/pop collection ISNT
the "local_part" of the email address
nobody will be emailing directly to them
they will only email to the alias
ive a small set of users (max 40)
i can see this not being ideal for massive mail domains
i thought it might be starting point for you
