Unique IDs have to be unique (therefore a mechanism that allows you to check the uniqueness of the ID). Note that one would have to come up with such a mechanism for email addresses as well but since it's already present. The problem is the following: Users want to login using their email address. Not unique ID a la compuserve, not john~example-com and other barbarian means. Just their email address and a password. I don't like any more than you do but that's what I have to come up with.

Now I have another question :-)) How do I manage to tell Postfix to treat "[EMAIL PROTECTED]" as a local username? What I mean by that is that right now I have translation done at the virtual table level under Postfix. [EMAIL PROTECTED] becomes something else (john~example.com let's say). I want to tell Postfix to accept all mails for [EMAIL PROTECTED] and "relay" them to Cyrus. Since Cyrus will have a [EMAIL PROTECTED], everything should be good. Please tell me if I am confusing you.
