Exchange 2003 SP2 Intermittently tells it's own users Relaying Denied
Here's an odd problem. Running SBS2003 SP2 with Exchange 2003 SP2. A user just received the following yesterday:
Your message did not reach some or all of the intended recipients.
Subject: RE: XXXX

The following recipient(s) could not be reached:
'Remote Recipient' on 1/30/2008 12:17 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<localdomain.com #5.7.1 smtp;550 5.7.1 <recip@remotedomain.com>..

User is setup to use Microsoft Exchange with no additional POP/SMTP profiles setup, so their Outlook client only talks to the Exchange Server. The Exchange server kicked back an NDR stating that the user in the local domain doesnt now have permission to send to the recipient. Looking at the SMTP log, it appears that it didnt even attempt to send the message to the SMTP connector, as the only references to the recipient e-mail was the second attempt, where the e-mail then went through. The only thing different the local user did the second attempt was put the recipient addresses in the TO field instead of the CC field.
Anyone have any ideas on this. I have another user who has reported this issue as well, and a second attempt at sending the e-mail is usually successful.

It's evident that the error was produced in the Exchange MTA, because I do see both messages in the MTA log, but only the successful send attempt in the SMTP log. I also found this link regarding the event ID codes:
http://support.microsoft.com/kb/821905
And it appears that the Exchange server got confused and tried to send to the wrong MX. There were three recpients in the e-mail, two of one remote domain, one of another remote domain. The Exchange server attempted to send the message to all three recipients to the remote domain that only hosted one of the recipients.
Three months ago I removed Symantec MS for Exchange and IHateSpam, I'm guessing there's a correlation to this problem and those un-installs.
Since your link referenced DNS and MX errors, and led me to my answers, I'll award the points.
