    I've followed the tutorial and everything works great. I've got my mail up and running (installed squirrelmail). I've setup thunderbird to recive the mails too, the problem is sending mail from thunderbird. In the maillog I can see that thunderbird connects, then it just hangs until it timesout.

    I can telnet to the server from the same computer thunderbird is installed on.

    The server is a VPS with an older kernel...

    2.6.18-028stab068.9 #1 SMP Tue Mar 30 17:22:31 MSD 2010 x86_64 x86_64 x86_64 GNU/Linux

    I got errors when I tried to install the "base" package. Everything else seems to work ok though..

    Any ideas? My guess is that my postfix configuration is off. But I've followed the guide all the way.

    That's ok. Are there any errors in your mail log?

    What are the outputs of
    Code:
    netstat -tap
    and
    Code:
    iptables -L
    ?

    Can you switch off the firewall for testing purposes?

    Did you check the mail log for errors?

    I've stopped IPtables.

    The maillog says that my IP (home computer) connected, then it just times out. It's like thunderbird connects to the server, and then the server dosen't know what to do.

    What about the mail log?

    As I typed above, thunderbirds connects then disconnects. No erros. Unless you mean another log then the maillog.log in /var/log/

    That's the correct log.

    Is there some kind of router between your client PC and the server that might block your requests?

    Is the server located in a data center, or do you host it at home/in your office?

    Yes, there's a router.

    The server is in a datacenter.

    The VPS runs on a virutozzo system. So the kernel is old. I could not install the "BASE package".

    I can connect via telnet to the box, and according to the maillog.log, the thunderbird client connects just fine.

    I'm thinking of just moving to another host that dosen't run viurtozzo, so that I can have my own "container" and run the newest kernel.
