Hello:
Yesterday was the first time I got to test my qmail system with
the big to-do patch applied.
Problem:
Some $%^* hijacked a T1 line somewhere and started spamming using a
return address that points to my system. The sheer number of bounces
generated, slows legitimate mail down on my system by 6 hrs.
I had applied the big to-do patch in hopes of fixing that. My local
concurrency is set to 40 and remote to 120. I had 4000 messages in my
mail queue but qmail was not delivering mail for about 3 hrs. I had about
45 qmail-queue processes. The machine had plenty of juice, the load av.
never shot up over 1.5-2.0.
Local/Remote concurrency never shot up, logs showed a max of
2/40 and 6/120.
Can anyone explain this? I want qmail to chew/hog the cpu and deliver the
mail. What am I forgetting to tune??
Thanks
Burzin
