Why can I connect to the server, to get my mail

    I'm new to this VPS stuff. We had Debian 6 running with Postfix and Courier.

    That worked well, until I had to reinstall the server. Now the mail applications can't connect to mail.domain.com. I have tried the old setup, and now followed the Debian 7 how to Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Wheezy).

    I just keep getting the message that the server can't be contacted. I haven't changed the DNS settings, when I ping mail.domain.com, it gets a response.

    What am I doing wrong?

    postfix or courier connection problem?
    Clear text?

    You will need more information and possibly a /etc back-up or?
    can you telenet the port?

    It seems Postfix is the problem. I can telnet and and send, via port 25. When I go to a different computer or my iPhone, I can receive now (I got that part fixed) but not send.

    I use Postfix, Courier (both with MySQL), SASL and TLS. I followed this tutorial, I did skip the Amvis, Spamassassin and ClamAV part. Instead of that I installed Dspam and ClamAV.
    I disabled the dspam lines in the Postfix master.cf, no change.

    I did use the FQD (not server1.example.com :D), it has worked before the reinstall, I changed nothing when it comes to the DNS.

    In case I need to share some config files, please do tell me which ones I need to share.

    I got it working. I found an older backup I made of the master.cf file.

    I have no idea why this one works, and they other one didn't, sadly.

    Silly question but have you forwarded all the applicable Ports? Sometimes we forget the easy stuff. I got 25, 110 and 143 all forwarded...
