I run the Ubuntu 6.06 setup, and ISPConfig.
My ISP is blocking outgoing port 25, I found that out after i moved ISP, and I'm now stuck with them until March.
So during the setup I configured procmail to use my ISP's mail server as a smarthost.
This has worked before with Exchange server.
It was also working fine, until I migrated to new server hardware.
I thought I had configured everything the same, but now I have 2 problems.
First one and so far most important, mail does not get delivered to my mail box, but rather gets bounced back after a while.
With an error message about too many hops.
(domains, IP and usernames replaced)
My config as following.
server hostname: lnx1.mydomain.net
my mail domain configured in ISPConfig: mail.mydomain.net
settings during setup of postfix: mail.mydomain.net
Mail sent to firstname.lastname@example.org
get's rejected with follwoing;
This is the Postfix program at host smtp5.myisp.net.
I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.
For further assistance, please send mail to
If you do so, please include this problem report. You can
delete your own text from the message returned below.
The Postfix program
<email@example.com>: host mail.mydomain.net[my.ip.add.ress] said: 554
Error: too many hops (in reply to end of DATA command)
My second problem is less important since I can use the relay host directly, but would be nice to avoid.
I'm unable to use my server to send mail.
Kontakt(Kmail) gives an error:
Your SMTP server does not support PLAIN.
Chose a different authentication method.
The server responded: "Error: authentication failed"
The message ........
However when detecting what server supports, it configured everything fine.
So I started looking in the logs, and this is what I see:
Jul 5 18:04:06 lnx1 postfix/smtpd: connect from unknown[192.168.1.5]

Jul 5 18:04:10 lnx1 postfix/smtpd: disconnect from unknown[192.168.1.5]
I should mention that the password is correct. :-)
Huff, long question, hope someone can solve it for me...
