Hi,
i upgraded one of our major mailservers to exim-4.12 + exiscan-4.12-22
yesterday and everything works smoothly except for one strange thing.
Sometimes relaying users are rejected with the following message:
temporarily rejected RCPT
In the main an reject-log the following appears:
2003-02-15 14:55:57 H=(hostname) [111.111.111.111] F=<sender-foo@???>
temporarily rejected RCPT <recipient@???>
So no reason is given, why these mails are rejected.
Both the recipient and the sender are valid Adresses working just fine. And a
few minutes later the same Mail simply works and is accepted.
I already turned off hostlookups and re-checked the configuration, but did not
find any suspicious things. The mails are not rejected by an ACL as far as i
can see. Since this behavior appears for a few minutes and disappears later i
can not go into debug mode an watch it, because i never saw it live.
One more interesting thing: this behavior occurs concentrated on a few minutes
and disappears after this for hours. So i have about 30 of these entries in
the log between 10 minutes and then it suddenly stops. But in this 10 minutes
time-slot other mails are successfully relayed.
Before i go into an in-depth analysis i would like to hear your comments,
since this is gonna take me hours.
Any ideas? Any suggestions? Do you need any further information?
Thank you
Andreas
