Sadly, I found that I needed to quit tilting at the 1GB memory windmill
and upgraded my tiny VPSs to 2GB for SpamAssassin + ClamAV + some other
milters.
You /might/ be able to get SpamAssassin in 1GB, but I don't know what
else will be on the system.
Clam is the memory hog. With a bit of tweaking you could run everything
else for a low-volume mail server in 256M - probably including webmail.
Here's a snapshot of my personal system colocated at work Notice that
clamd is third in line to gobble up RAM after a couple of VMs... and
that's strictly with stock signatures. SpamAssassin is also mostly
stock, although I think I bumped the spamd child limit up from default.
