Hi,
I've got quite a strange problem.
A user is trying to send email to a domain, "tn.odessa.ua" which has 3
MX servers. One of them is clearly not working,
"notes.uptel.net[195.138.170.139]", which has a priority of 30. Checking
the logs I see that Postfix always tries to deliver to
"notes.uptel.net", and only that one, for the past 9 hours.
Also, "n1.uptel.net" isn't accepting connections on port 25.
But "relay.uptel.net" is accepting connections and we had a succesful
email sent from another of our servers using that MX.
I've checked resolv.conf in chroot, it's correct. Using dig I get:
;; ANSWER SECTION:
tn.odessa.ua. 3000 IN MX 30 notes.uptel.net.
tn.odessa.ua. 3000 IN MX 5 n1.uptel.net.
tn.odessa.ua. 3000 IN MX 20 relay.uptel.net.
;; ADDITIONAL SECTION:
notes.uptel.net. 438 IN A 195.138.170.139
n1.uptel.net. 435 IN A 195.138.160.145
relay.uptel.net. 437 IN A 195.138.160.43
Postfix is configured with:
smtp_mx_address_limit = 20
smtp_mx_session_limit = 5
(Checked using postconf -n).
I restarted Postfix and flushed the queue a few times, but there isn't
any change. It's always trying "notes.uptel.net", never any of the other
2 MXs.
What should I do?
Thanks.
