I recently did an sbs migration from sbs 2003 to sbs 2011. On the 2011 box I installed ColdFusion 10, but I cannot get my mail server verified in the administrator. I am able to telnet newserver.domain.local 25 successfully, however I cannot use that same server name in the CF admin to connect to the mail server. I keep getting the error "Connection Verification Failed! " in the CF Admin when I try to verify the mail server. I noticed an error in mail.log that says: "javax.mail.MessagingException: Unknown SMTP host: oldserver.domain.local; nested exception is: java.net.UnknownHostException: oldserver.domain.local". The old server name is being used and I do not know why. I've been through all the sbs migration steps to clean up DNS so I'm not sure where ColdFusion is getting that old server name in the Unknown SMTP host error. I double checked DNS did a flushdns and restarted ColdFusion, but no luck so far.
If anyone has any other ideas how to troubleshoot this I'd greatly appreciate the advice.
