Hi, After many years of hassle free use from our email system we are now getting a rather odd disconnect as shown below.
May 3 16:07:36 spambox nss_wins[14039]: connect from sender.remote.com[1.2.3.4] May 3 16:07:38 spambox postgrey[2865]: action=pass, reason=client AWL, client_name=remote.remote.com, client_address=1.2.3.4, sender=john.sm...@remote.com, recipient=u...@destination.co.nz May 3 16:07:38 spambox nss_wins[14039]: 0518C62E981: client=remote.remote.com[1.2.3.4] May 3 16:07:38 spambox postfix/cleanup[16322]: 0518C62E981: hold: header Received: from remote.remote.com (remote.remote.com [1.2.3.4])??by spambox.co.nz (Postfix) with ESMTP id 0518C62E981??for <u...@destination.co.nz>; Fri, 3 May 2 from remote.remote.com[1.2.3.4]; from=<john.sm...@remote.com> to=<u...@destination.co.nz> proto=ESMTP helo=<remote.remote.com> May 3 16:07:38 spambox postfix/cleanup[16322]: 0518C62E981: message-id=<5C82EDFA9CB70146A77EB00A438DC6340B7614DB@LCL-SBS.RemoteServer.local> May 3 16:07:39 spambox nss_wins[14039]: lost connection after DATA from remote.remote.com[1.2.3.4] May 3 16:07:39 spambox nss_wins[14039]: disconnect from remote.remote.com[1.2.3.4] What is frustrating is that is is not occurring every single time, some emails from this domain pass through with no delay, other times it drops the connection and the sending server queues it and tries again. There are two mail servers that send to clients on this system that are having the issue. Both of the servers are running Mail Marshal (if that's any help!) I have done some research on the "lost connection after Data" and many articles refer to loss of network connectivity which we have tested and is not the issue. Others refer to incorrect, or lowering the MTU of either NIC or Router (have confirmed this is also not the issue. I would be interested to know if anyone else has had a problem like this. -- View this message in context: http://postfix.1071664.n5.nabble.com/Postfix-lost-connection-issue-tp57670.html Sent from the Postfix Users mailing list archive at Nabble.com.
