I run a (proper!) ISP in the UK, and do a lot of network/systems admin work.

comment Create IP nullroute blacklist from text file
Something like CSF configserver.com/cp/csf.html can work with a black and whitelist as well as do bruteforce detection/banning with the right config. It can be made to work on Debian just fine.

You're still going to need something automated to catch the offenders in the first place if they're not already coming from "known" proxies/open relays. Assuming you're running a compatible IRCD and know enough to compile and run it, how about S from QuakeNet's newserv to monitor the most commonly spammed channels?

Is it actually a concerted attack to disrupt the operation of the forum, or is it just "regular" forum spam from lots of different IPs?

Also, 8.5GB free out of what? If it's a large volume, that might be low enough to stop Exchange functioning normally on it's default thresholds - see technet.microsoft.com/en-us/library/dd146168.aspx

It'd be useful if you could give me an address at the domain to test sending to, and then I can see what appears in the mail logs.

Best to update your original question with the extra details rather than burying them in this thread, too :)

Also: Is it worth burning hours on troubleshooting this issue vs giving him a different, freshly installed machine?

a bit more detail on exactly what you tried tuning would be useful. What's the latency over the link? Does this member of staff have a non-standard software image or is everyone running identical cloned machines? What happens if you run some tests using iperf?

HYB39S256400DT-7 are supposedly 256Mbit which means you'd need 8 of those to make a 256MByte memory module. You sure that they're not on both sides of the module? I can't find anything on a "HYB250256800CT-6" but I'm guessing they're supposedly 256mbit as well (the 256 in the part code would give that away) but you'd need 16 of those to yield 512mb.
