I have found on my Suse 8.2 System with Postfix runing in my mail log file the following periodical warning (exactly every minute)

"server postfix/nqmgr[10175]: warning:connect to transport smtp:Connection refused"

Anyone an idea why the postfix queue manager do this every minute ?

Thanks !

It's doing this every minute because the transport_retry_time is set to 60 seconds :-)

But this is probably not what you wanted to know. So let's find out what's wrong with your system:

Is mail still getting delivered?
Do you have any idea when your system started to print this message? Was it after a change you made to the postfix config files?
Did you manually change the postfix config files?
Is the mydestination variable set correctly to all your hostnames?

Thanks for the answer.

I can receive emails without any problems.

The problem starts without any (known) reason. I have changed nothing.

Yes, I manually have changed the postfix files - but for over a mouth everthing works :-)

when I try to send an email, I find it in /var/spool/postfix/deferred:

A.client_name = unknown (-> no dns possible, this should not be a problem ?) A.client_address = 10.10.0.254 (this is my router)

mydestination = $myhostname, localhost.$mydomain, $mydomain

Is the myhostname variable set correctly?

To me it seems that your queue manager tries to connect to an smtp server, and is not allowed to do so. Something must have changed since you first set up this machine. These messages don't just start without any good reason.

Did you change anything else in the network setup? Why is it reporting an error with your router address? Are you trying to relay your emails to the router (which would probably be wrong)? Is the setting of relayhost correct? If you put the hostname into square brackets, postfix will not try any DNS lookup:

relayhost = [smtp-server.your.provider.com]

Are email messages going out as well?
