Perhaps Outlook uses MAPI for message submission as well as for message retrieval. Can you telnet to port 25 on the Exchange server? Open Terminal and type: telnet hostname.exchange.dom 25 Do you get a "220" response back from the server (Type "quit" to end the telnet session)? If not then, either the server doesn't have the SMTP service enabled, or you are having firewall issues. If you can telnet to port 25, perhaps the Exchange admin hasn't allowed SMTP relaying from your subnet. If Outlook submits messages via MAPI then this oversight wouldn't affect them. -Remo Del Bello -- "Yet even the most subtle spiders may leave a weak thread." - Gandalf the Grey in "The Lord of the Rings: The Fellowship of the Ring" -- To unsubscribe: <mailto:[EMAIL PROTECTED]> archives: <http://www.mail-archive.com/entourage-talk%40lists.letterrip.com/> old-archive: <http://www.mail-archive.com/entourage-talk%40lists.boingo.com/>
