    I am having an issue and to my knowledge it is only with Yahoo. They are the only emails in my postfix mail queue.
    I have contacted Yahoo, but they have yet to respond.
    Thank you in advance.


    Here is a section of my mail log:

    It isn't, that was one of the first things I checked.


    I did figure out what was causing it. But don't understand why to some mtas and not others.

    The firewall I had in front of it was blocking it some how, although I have port 25 open, I could not telnet from my server to yahoo's on port 25. That is until I opened up all the ports on my firewall to the server.

    Any thoughts?
