If you have Port 25 access to the internet (ie your ISP doesn't trap it and require you to go through their servers), you can try telnetting into the rejecting server on Port 25, try to get it to accept a message and see what responses you get. You would of course need to know how SMTP works and what commands to issue :-) If you want to send me a copy (with complete headers) of an original message and a bounce, I can look into it further for you. -- Stuart
