Make sure you can still connect to the SMTP server from the web server (not via CF).
You can test this with telnet Open command prompt and type telnet yourServerName 25 if you get a response back from the server then it works, if not, then there is a problem connecting to the server, not a CF problem.

When I use CF Admin to verify Mail connection it reports Success. However, all mail is being marked undeliverable and the error message I'm getting is "Unknown SMTP host: our mail server name" Anyone know how to resolve this? Thank you in advance. :-) Dawn ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:339498 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
