Hi all,

I'm running two directors with lmtp proxy as relay transport for my mail exchangers.

relay_transport = lmtp:inet:dovecot-directors.example.net dovecot-directors.example.net resolves to 172.17.1.3 and 172.17.1.4

Now, .3 is down and Postfix tries to deliver it to .4 but this connection gets a timeout:

(delivery temporarily suspended: connect to 172.17.1.4[172.17.1.4]:24: Connection timed out

There is no log entry on the director.

Can anyone give me a hint how to solve this or maybe optimize my configuration?

Regards Patrick
