Don't know how to read this myself, but: Statistics from Tue Mar 22 04:02:04 2005 M msgsfr bytes_from msgsto bytes_to msgsrej msgsdis msgsqur Mailer 1 0 0K 2 5K 0 0 0 *file* 4 278979 15161686K 35934 2469132K 15337 0 0 esmtp 9 90443 6159872K 321265 17753356K 742 0 0 local ===================================================================== T 369422 21321558K 357201 20222493K 16079 0 0 C 1471804 78356 16079 I installed greylisting (relaydelay) June 5th last year, so those statistics include a few months more than greylisting has been running. Note that the msgsrej is not a measure of the # of tempfails.
