You could setup a virtualdomain loop and run everything through a
simple .qmail that uses 822header (or similar tool) to check if
there's an X-SPAM header or something and dump it into a mailbox.

A 200MHz Pentium can easily handle 20Mbps of traffic, and that's the
kind of junk most techie people have a few of in the closet. Having
been through a lot of nasty stuff in the last 8 years, a router or
bridge with a firewall has saved me hours of time and pays for itself
inside of a month.

I also quite understand being limited to hardware one has on hand. The
supply chain around here has taught me to be quite a packrat and
hoarder. There were times that I could assemble entire machines out of
stuff I had hidden in my desk. Now, I've got a spare Opteron 246
server with an LSI MegaRAID 300-8X SATA, and the only power supply I
have is a weedy 250W that barely manages to turn the CPU fan. Been
waiting a month now to get my hands on a new power supply. Hmm... one
of the web guys just got a new machine, lemme go find my screwdriver.

At one point I was writing a book based on my job, tenatively titled
"How to SysAdmin for $10/day"
