For a few days me it is impossible to send e-mails to certain domains with my servant exchange 2003. After sending the mail the system manager returns a message to me where it indicates that it is not possible to deliver the above mentioned message and the mistake to be " 5.5.0 smtp; 554 Transaction Failed Spam Message not queued ". I have looked if my IP is in black lists, consulted with the owner of the domain if it has my own domain as spam, etc. For what I see the messages they do not go out of my servant.

Thats not an Exchange error. Do you smarthost to your ISPs mail server? I would check with your ISP regardless, or whomever you are using to send email messages through.

I have checked my SPF records, PTR records, and FQDN and all looks good. I am not on any RBLs and I only have an issue with one domain I'm trying to send emails to. The server generating the message is my edge transport server, NOT the recipients server. The message isn't even hitting the internet. It dies at edge transport.
