I just replaced our win 2k /exch 2k server with a new dell with SBS 2k3 which uses exch2003 sp2. I migrated all mailboxes with exmerge and all is well on that front.
My problem is that when users send mail to certain domains, we get a delayed message. Those domains are MSN.com, Hotmail.com and hewittoneil.com along with a few others. Sometimes the mail goes through after hours and sometimes it does not.
I am the IT consultant for hewittoneil.com and we don't use any blacklists and we do not have any restrictions on receiving mail to that server. And, we were able to send to them and MSN and Hotmail on Friday before I switched the servers.
Our mail server is mail.wavelandgroup.com and we have the appropriate reverse DNS records so I think it is something in the exch2k3, but I don't know what.
I know exchange but have never needed to use the logging feature. is there a log that I can turn on to help me see why the messages are being delayed? Can I log the incoming at hewittoneil.com to see if the message is reaching that server and why it was sent back or even if it reached that server?
I searched for previous posts and followed their recommendations such as excluding the exch folders from the symantec anti virus and checking my dns. None of that seemed to help. Does anyone have any other suggestions?
