Title: הודעה

Hi all,

I don't have the solution, but I can add to the problem ;-) I see the same errors.

 

########### Example 1:

Logfile says:

Dec 21 09:27:26 jupiter courieresmtpd: error,relay=::ffff:12.254.210.137,from=<a[EMAIL PROTECTED]>: 417 DNS lookup failure: no-kidding.org.  Try again later.

 

Manual DNS query says:

jupiter:/var/log# dig @localhost mx no-kidding.org

[...]

I'm getting weird messages in logs when messages pass through fetchmail or esmtpd module :

 

Dec 25 18:00:15 web courieresmtp: id=00075158.3C28A037.00000623,from=<[EMAIL PROTECTED]>,addr=<[EMAIL PROTECTED]>: DNS lookup failed.

Dec 25 18:08:00 web courieresmtpd: error,relay=::ffff:10.0.0.150,from=<[EMAIL PROTECTED]>: 417 DNS lookup failure: fredy.dyndns.org.  Try again later.

it started suddenly and i have no idea why..

when i do normal dns work, i see the dns resolving is working just fine, on the domains courier complains about as well....

any ideas ?
