CFMAIL problem - only some mail doesn't get through

[snix1]

Hi! I have an application that sends out email messages to many different domains. One particular domain never receives the cfmail messages. I am able to send messages to this domain using Outlook o.k. and all other domains get the cfmail messages fine. The domain's tech person says that the cfmail messages never get to the "front door" as he sat there and watched mail come through. I've looked through the CF Administrator pages and don't see anything there to help me. The cfmail messages are bounced back to me as Undeliverable. Everyone else gets theirs. Has anyone seen anything like this before? By the way, I get nothing in the error log.

Thanks!!

Hey Snix,

If you're receiving a bounce back message, that would indicate that CF has passed it off to the mail server and the mail server was not able to send the message. I would examine the headers of the bounced message for any clues as to why it was bounced. It's possible the mail server might be blocked by the other domain's mail server it that server is using one of those idiotic anti-spam black lists.

If you use the same server as CF to send your outbound messages and you can send to the address, there should be no reason that you can send and CF can't. If however you use a different server, change your mail client to use the same one CF does and see what happens when you try to send to that address.

If none of this helps, post the complete headers from the bounce back message as they may give us more of a clue why it bounced.

Good luck,
GJ

Thanks for your reply, Gunjack. I'm not sure I have access to the message header. Does it look something like this?

Hey Snix,

The message headers would be in your bounce back message. Most e-mail programs hide the full headers and you have to explicity show them. That's where you would typically see an error message indicating why the destination server refused the message.

Thanks Gunjack:
It turns out the problem had something to do with the firewall. I'm out of my element here, but it has now been corrected; thanks for your help.
