I know, very big increase in spam.
It is likely caused by a botnet infecting many people, but I haven't seen any reports of it on any news sites.

The total volume of email has increased a lot in the last 2 months, and with that a steady increase in spam slipping through the filters.  The amazing thing is that some look like the same email over and over, which you would think the filters would catch. I suspect that each one is slightly different in just enough of a way to get past the filters.

This is not just affecting our servers. I have noticed a lot getting through Google's Postini service, which is a major spam blocking service. So, if Postini is have troubles keeping up, then I can't bang my head too hard.

I'll be tweaking the filters and server settings to see if I can tighten up a little, but the usual process is that the filters and blacklists catch up and start blocking better. Right up to when the spammers find another way to attack.


Nothing is more expensive than trying to save a buck.
