I'm using Exchange 2003, sp2 and also Trend Micro's Client Messaging Security on this server.

No one from this company can send out to a Quest account which uses q.com as the domain name.

I understand some of the problems with 1-3 letter domains. Is this problem internal with Exchange, something in Trend Micro or am I looking in the wrong places.

The error meassage is below, but seems vague to me:

Your message did not reach some or all of the intended recipients...

The following recipient(s) could not be reached:

Unable to deliver the message due to a recipient address failure. Check the recipient address and try again.The MTS-ID of the original message is:c=US;a= ;p=Companyname;l=EXCHANGE-071006201308Z-12460

Thanks in advance.
