Hello,
I have list servers that send mails through another relay servers. With
this configuration all mail sent from our mail servers are delivered
through our relay servers. All servers use postfix (list servers use
2.7.0 and relay 2.5.5)
We are having problems with dns lookups to one domain. I know is not a
postfix problem, but a dns configuration error in that domain. But it is
affecting our servers.
The problem is that whenever the relay server receives a mail directed
to that domain, I get the error "conversation with <mail server> timed
out while sending MAIL FROM". And as list server group messages, all
recipients in that group as rejected.
I've been looking for the problem on that domain and is a timeout
problem. Due to some problem in its configuration, I've never have an
answer (the domain exists, but it doesn't answer).
So I would like to configure some kind of dns lookup timeout in my
relay servers, so if the query is not answered I could reject the
message with a dns error instead of timing out the connection.
Is this possible? How?
Thanks,
