    >Has anyone tried compiling SpamAssassin or writing a faster version of it in another language?
How fast to you want it? I've been pumping roughly 20,000 emails per day through Spamassassin via maia[0], on a relatively moderate VPS. greylisting in front of it handles a huge portion of the load.

Edit: Been a while since I checked. Actually yesterday's number was 98,000.

It's been made clear to me now that I need to look closer at greylisting in postfix before mails are passed to the proxy_filter.

But if you're interested I'm talking around 62k mails a day. My experience with this amount has led me to use 64G RAM on each MX but that's only to handle a certain incident with very high load. Usually RAM usage is much lower than 64G and there's plenty of IO cache available.
