There are many reasons as to why yahoo.com would block you.

- Your IP is listed somewhere in a real-time blackhole list (RBL).

- Your mail server has no reverse DNS set (although I'm not aware that yahoo checks for reverse DNS).

- Your mail server isn't using an IP address that can be resolved to your domain, or somehow is using a different IP address in the mail headers than are being sent to yahoo, and yahoo thinks you're spoofing your IP address.

Testing between your own servers has little relevance other than you can send mail internally. Sending externally - as you've seen - is much different. <G>
