Hi Folks, We've had this today filling the logs on our server.
Turns out the MTA is returning 552 but observing the SMTP session reveals that the 552 isn't getting back to the client. The client reports 421 connection dropped. Client is Exchange 2010 using authenticated SMTP. The same session is used to deliver any other queued messages until it gets to this message where the session drops. 2014-11-11 09:48:13 m1-99293-00962 [Worker_4] [TLS-in] 1.1.1.1 <[email protected]> info: found message size announcement: 67.12 MByte 2014-11-11 09:48:13 m1-99293-00962 [Worker_4] [TLS-in] 1.1.1.1 <[email protected]> message proxied without processing - message size (70382399) is above 500000 (npSizeOut). 2014-11-11 09:48:13 m1-99293-00962 [Worker_4] [TLS-in] 1.1.1.1 <[email protected]> warning: got reply '552 Message size exceeds maximum permitted' from 127.0.0.1 2014-11-11 09:58:13 m1-99293-00962 [Worker_4] [TLS-in] 1.1.1.1 <[email protected]> info: no (more) data readable from 1.1.1.1 (connection closed by peer) - last command was 'MAIL FROM' 2014-11-11 09:58:13 [Worker_4] Disconnected: session:7FD9B0EFE5C0 1.1.1.1 - command list was 'EHLO,STARTTLS,EHLO,AUTH,MAIL FROM,RCPT TO,DATA,MAIL FROM' - used 18 SocketCalls - processing time 604 seconds Any ideas why the 552 wouldn't be passed on?
