delays=193728/38/0/0.1 http://www.porcupine.org/postfix/doc/big-picture.html
http://www.postfix.org/postconf.5.html The format of the "delays=a/b/c/d" logging is as follows: - a = time from message arrival to last active queue <http://www.postfix.org/QSHAPE_README.html#active_queue> entry - b = time from last active queue <http://www.postfix.org/QSHAPE_README.html#active_queue> entry to connection setup - c = time in connection setup, including DNS, EHLO and STARTTLS - d = time in message transmission Does "message arrival" also mean "pickup" in the flowchart? where it enters Postfix? My thinking is spam filters are the delay cause here, in the "cleanup" process? But a colleague says it is our server sending slowly...but that doesn't make sense..., how is the receiving server going to know of delays by the sending server, if not logged in c/d? Thank you in advance
