Hello all, On one of the systems I administer, I have a strange problem I can't really get a grasp of why it happens.
Maybe one of you can help me out here. It started when we noticed the following block in the exim log in the server, which act as an smtp outbound server on the infrastructure: (I anonymized the email address it goes to, but I tried to leave as much information as possible intact - I just don't have the liberty to write it non-anonymized) [EMAIL PROTECTED] exim]# exigrep [EMAIL PROTECTED] * 2008-10-06 10:07:02 1Kml7N-0006mb-SY <= [EMAIL PROTECTED] H=cpe90-146-29-228.liwest.at (auerad1a8f42f7) [90.146.29.228] P=esmtpa A=fixed_login:uid=hklvappx S=1822 [EMAIL PROTECTED] 2008-10-06 10:07:07 1Kml7N-0006mb-SY == [EMAIL PROTECTED] R=dnslookup T=remote_smtp defer (-44): SMTP error from remote mail server after RCPT TO:<[EMAIL PROTECTED]>: host mail4.internic.at [212.126.66.30]: 450 <[EMAIL PROTECTED]>...

And there are much too few delivery attempts in the time for the retry configuration to justify a hard bounce / message freeze for the first message anyway. Can anyone provide some hints what and why it is happening here? Do you need some more information like configuration of the Exim? Or is there any tool I could run to gather some more information about this? The Exim running here is a 4.66 on RHEL 4. Thanks in advance for you time and help!
