From: Eddy Ilg on 2 Jul 2010 00:42 Dear postfix users, I am struggeling with the concurency limit of postfix. We are using two postfix MTAs. MTA one wants to deliver to MTA two and has 300 mails in the queue. Trying to flush the queue always results in the error warning: Connection concurrency limit exceeded: 11 from xx[w.x.y.z] for service smtp on MTA two. I tried excepting MTA one in the config of MTA two from the limits as follows: smtpd_client_connection_count_limit = 30 smtpd_client_event_limit_exceptions = $mynetworks, mta.one Somehow, both of these parameters have no effect. Note the 11 in the message above. Are these the wrong parameters? How do I enable MTA one to open many connections? (disable limit?) Best regards, Eddy Ilg |
