    Postfix Problem or somethin'


    I get this error when I try to use my postfix server for sending using outlook express. I get the same message outside the internal network and inside of it. Different users get the same message, I just installed it and I'm not quite sure what I'm doing... Here's the message:

    The connection to the server has failed. Account: 'Home Server', Server: 'thetechbox.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

    I've got to also make it so people can send from outside the internal network if possible.... with secure login or something... Help Please =P.. Thanks in Advanced...

    -Matt

    10061... how useful those Windows error messages are... anyway, 10061 means Connection Refused in plain language, which means that there is no socket listening at the address that you're trying to connect to. Either postfix isn't running, or it's only listening to the localhost address.
    Check with "netstat -ant | grep 25" to see if, and in that case where, postfix is listening.

    I did a netstat -ant | grep 25 and it says "tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN" which I assume it's not listening on the network card IP which is 192.168.0.66 (it's port forwarded, and yes I'm forwarding 25)

    Yeah, 127.0.0.1 is the loopback interface, so it can currently only be accessed from the machine itself. I haven't used postfix myself, so I can't help you reconfiguring it, but look through postfix's config files and see if you find anything about what address it binds to.

    OUtlook says it sends the mail, but then I get a mail daemon message back a few hours later, Here is the contents of it:

    Have you configured the server to use the right DNS servers? Check /etc/resolv.conf.

    In my resolve.conf it shows:

    Code:
    search san.rr.com local
    nameserver 127.0.0.1
    nameserver 24.25.195.3
    nameserver 24.25.195.1
    The problem is I don't know how this file works or what it does, so I need help with that. I do know that this server is behind my router, meaning it has a private ip and it serves the net via forwarded ports. Is it supposed to use my router (192.168.0.1 internal IP) as a nameserver? Oh yea, and I can resolve addresses just fine... I can ping google, hotmail, yahoo, linuxforums, etc.

    Interesting. Then it's probably something with Postfix. If that's it, I cannot help you, since, like I said, I haven't used postfix myself. It would seem that your resolv.conf is correct since you can ping sites by their names. Try mailing to bockmanmatt@mx1.hotmail.com and see if you can get through with that address.

    Can someone who knows a bit about postfix help out here?
