No. SIMS relay restrictions are based on IP address only. However, one of SIMS anti-spam features is to check the validity of return-paths. If, as seems likely, Communicator uses the e-mail address set in its preferences as the return-path for messages, SIMS could well be having trouble looking up the domain. That would be consistent with Chris's theory. Christopher Bort
