Exchange 2003 SP2.
Users get an error 550, recipient address rejected.  no such user if
they try to relay through the mail server.  I'm doing tests using
Outlook 2003 setup for IMAP.  I enabled the advanced settings to require
authentication on the outbound mail server., and the default relaying
options are enabled which should allow this to work.  I double-checked.

I must be missing something obvious here?
