Postfix: error header counts exceeds maximum

[rtenklooster]

Hi everyone,
I spent my evening setting up my mailserver.
i followed this (http://http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04) 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 mail.kpnplanet.nl[213.75.63.13] 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

Thanks in advanceThis 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.
