I have a need to run a server with virtual mailboxes that can have identical username portions of [EMAIL PROTECTED] for a variety of domains. My initial solution was to simply have the users login as [EMAIL PROTECTED] after removing some checks in the source code, I now see that adding users is done with a period to differentiate between folders. What's a good way to overcome this virtual mailbox with identical username issues to keep the login names consistent for the end user (i.e. keep support calls down). I've done this before when building large webmail systems by using "user123919231274" as the login name, with their logical username mapped to that kind of wacky string. But that wont work in this scenario. Any ideas? Your haste is appreciated greatly! -- Robert
