[Greylist-users] Database performance

[Wayne Walker]

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*

=====================================================================
 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.
