I keep getting mail messages bounce with the following error:
 
Unknown user: [EMAIL PROTECTED] 
 
while the mailbox is a good address and nothing is wrong on the other end.
 
What's happening?

That seems to be a solution until IPSWITCH decides to take on this issue
can we use MS smtp service or the Imail Express (free version) on that
