    Tried to telnet 25 to the server from behind the router couldn't connect. I could connect to it locally however.

    Code:
    C:\Documents and Settings\username>telnet 192.168.0.115 25
    Connecting To 192.168.0.115...Could not open connection to the host, on port 25:
     Connect failed
    Code:
    # telnet localhost 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    220 server.slccr.org ESMTP Postfix
    ^]
    telnet>
    so the problem must be postfix, no?

    Are you running any sort of firewall on the server (never mind the firewall on your router)? If so you may have to tell the firewall to allow connections through port 25 (in and out maybe).

    Could you also explain your problem a bit more? In the first log file you posted, that is a log from when you tryed to send a message locally to a hoymail user? And this also happens when you try to send mail to gmail users? What about other domains?

    I have the firewall turned off. I can't send out any mail or recieve any mail. I've tried sending to hotmail, gmail, mckendree.edu, and htc.net. I think the problem has to deal with my server though and its not accepting any connections on port 25 e.g. telnet

    Is the server only being refused by Hotmail.com? If so, this may be the result of Microsoft's reverse lookup on your mail domain. Is your domain properly registerd and are you sure that it isn't blacklisted. The reason is, this could be the cause of your server failing to send.

    I never thought of that. I wonder what could be blocking access to his mail server on his local network?
