| Subject: | Post Mortem - Matronics List Pummeled By Spam... |
Dear Listers,
Over a 3-day period, Thursday 11/8 though Saturday 11/10, the Matronics Lists were
pummeled with over 450,000 spam emails causing posting delays and a few duplicate
messages. Yeah, I really said nearly half a million spams! The good
news is that I don't believe a single one of them actually made it to the Lists
thanks to the aggressive List filtering code and the Barracuda spam filter.
The bad news was that it caused quite a back log of email messages starting Friday
and continuing until late Saturday when I noticed that delivery seemed a bit
sluggish. By about 11pm on Saturday night, I had managed to get the backlog
cleared out of the spam filter by temporarily adjusting some of the filtering.
A check of the queues this morning, and everything looks like its working great
and there are no incoming filtering delays and spam levels appear to be back
to "normal".
There were a number of people asking what was going on, so I thought that I'd send
out a follow up post mortem on the event...
November is the annual List Fund Raiser. Your contribution directly enables me
to buy systems like the Barracuda spam filter that keep the List free of that
garbage. Please make a contribution to support your Lists!
