Jason,
Something is wrong with your config.
I think of an autoblock as something that is temporary
and short term. A block for no more than an hour or
so, for example.
It sounds like BI wasn't removing the entries
automatically after a specified interval.
I keep my interval at 1 hour because it is enough to
hamper the spammers but not so long as to potentially
block a valid emailer. There is no way I'd ever have
50,000 IPs in my list after 1 hour.
==================================================
I've been running for a while with BI set to auto
block for 3 months these
harvest attempts. At first it seemed to be a
blessing, but after the
firewall.ini file grew to over 50,000 IP addresses
(and by that nature
50,000 lines of blocks), BI begain killing our mail
servers performance.
Processor utilization went from bouncing back and
forth between 1 and 40
percent(large mail), it stayed at 100% and mail
transfer suffered greatly.
I just cut out 90% of the blocks in the ini file, and
utilization went back
to normal. Seems that BI doesn't cache this
information which is very bad.
It would be much better if it would keep the file in
memory until the file
needs updating, then do a write/cache update and keep
trucking.....Time to
go back to the drawing board....
Regards,
Jason
