I have 2x36 u320 15000rpm and 2x73Go u320 15000rpm and 4go memory.
The server received more than 1 000 000 each weeks, 98% spam, more than 250000
clients rejected (before spam filtering) each days.
We do not understand what append, why an idle server, put the mails in the
incoming queue and the queue manager take lot of time to process de mails, on
our test server (very very idle) when I injected 100 mails 20 parallel of 5k
(2s) all the mails are in the active queue, I have no mail in the incoming
(total process 15s), on the prod where there is activity the mails go to the
incoming.
The information is too skimpy for this we need your help, we are trying for
several weeks, lot of configs changes in_flow_delay, default_dest...,
smtpd_error_sleep_time = 0s, increase/decrease postfix/puremessage process,
install local dns... without any success some time this is very bad we are in
the fog...
