After a large upgrade of many packages on Ubuntu Karmic, postfix has stopped
working properly. Symptoms:
lost of
postfix/smtpd[5922]: warning: 224.90.55.65.bl.spamcop.net: RBL lookup error:
Host or domain name not found. Name service error for
name=224.90.55.65.bl.spamcop.net type=A: Host not found, try again
and, on every message coming in, rejection:
postfix/smtpd[5916]: NOQUEUE: reject: RCPT from unknown[65.55.90.236]: 450
4.1.8 <mun...@hotmail.com>: Sender address rejected: Domain not found;
from=<mun...@hotmail.com> to=<recipient-mun...@mungeddomain.invalid>
proto=ESMTP helo=<snt0-omc4-s33.snt0.hotmail.com>
dig and nslookup work from the command prompt, both as root and a
non-privileged user.
As far as I can tell, I am not running chroot-ed.
Postfix version is 2.6.5; I'll post postconf -n if it helps.
Where do I start troubleshooting?
Thanks!
Thanks!
