    Hi everyone,
    I spent my evening setting up my mailserver.
    i followed this HOWTO exactly, and almost everything seems to bee working.
    When i connect to my own mailserver by imap, with evolution, and try to send a message to my gmail adress, my isp does not accept the message.
    I am receiving the following message:

    host[] said: 552 Your
    "received:" header counts exceeds the maximum setting. (in reply to end of
    DATA command)

    Is there any way to increase the header count? Btw. I am using my isp's relay server becouse port 25 is blocked.

    Yesterday i was able to send mail trough this relayserver, by a previous installed postfix mailserver, so i expect the problem is in my configuration.
    I would be glad if anyone can help me solving this problem.

    The second problem is, i am not receiving mail from the internet, while my postfix configuration has inet_protocols = all

    The third problem is when i login to squirrel, i get a blank page. Just blank.

    Thanks in advance

    What's in your Did you ask your ISP why you see this message?

    Please make sure that your MX record is pointing to the right server.

    This probably means you made a syntax error when you modifed the SquirrelMail files (probably the config.php of the change_sqlpass plugin).

    1. I have my ISP not asked why, i searched my isp's website and figured out they where having 2 relay servers. I tried the other one, and it worked. so the original problem is solved.
    2. I was thinking my ISP only blocked outgoing acces by port 25, but i figured out, it also blocks incoming (mail on port 25) I had to configure a mail relay server for incoming mail, and reconfigure my server dns file.
    3. thanks for your comment. I will check squirrel's configuration again.

    Thanks a lot, also for the super good, advanced howto! it helped me a lot, configuring and UNDERSTANDING how postfix, ubuntu and mail servers work.
