RE: Strange 550 error
Jim - The customer is not on optonline.net, is not listed at ordb.org, there has not been any spamming coming from this domain from this server, and the problem is sporadic - so I don't think that's the issue. And what's you got against Optonline.net :) Although the owners won't let us watch the Yankees (can't get it on cable here on Long Island!), they give kick as* Internet speeds.

RE: Strange 550 error
Chris - Thanks for the info - looks like it could be an MX issue as the MX record for the customer points to oldcustomername.com not newcustomername.com (although both names are still valid). FYI - If you check out MSKB 284204, it does say that 550 maps to a "Generic protocol error (SMTP error)". Any suggestions on how to use the info in rfc821 to determine what the issue is and why it is sporadic?

RE: Strange 550 error
Thank you, that's a very good point. The MX record for the customers domain is actually mail.oldcompanyname.com, not mail.newcompanyname.com even though the IP address is correct. Thanks again!

RE: Strange 550 error
Bill - The mail was not coming from optonline.net, but from a customer site using a different ISP to another domain. I didn't change the error at all - it's a copy and paste from the log. I didn't post the domains as I'm not sure if the customer would appreciate it in a public forum. As for Optonline, it is a cable modem provider (excellent speeds!), but it does allow people inside the network to relay - send out messages with no regard for where it is coming from or where it is going to. If I'm NOT inside this network though, it does not allow relaying.
