Hello,
I have a recurring problem with my mailserver redelivering the same email over and over again to itself, until it gets entirely overloaded.
I am not sure what triggers this, it seems that mostly some incoming spam emails might be to blame. I guess there is an underlying configuration problem that needs to be fixed so that these loops will not happen any more, but I don't know where to look.
Attached below is an email header of one of those emails that shows how the message is looping: Received: from smtp2.mydomain.com (localhost.localdomain [127.0.0.1]) .... Received: (from root@localhost)
smtp2.mydomain.com and localhost is the machine...
Can somebody tell me what I can do to prevent these loops?
This is using sendmail 8.13.8-2, procmail 3.22-17.1, and cyrus-imapd 2.3.7-8.fc6 from Core 6.
Thanks,
MARK
