If you don't need SA on every email, _and_ if you're also doing
relatively time-consuming stuff in other slaves (eg, virus scanning,
or doing DNS lookups), it might help to use spamd/spamc instead of the
MD-builtin SA.

This way, you'd save some memory by not having SA in every MD slave.

For example, I have a max of 50 MD slaves on a machine (at 15MB/slave),
but only need around 15 SA slaves, max. That setup is highly dependant
on our particular situation in which we do relatively heavy virus
scanning, and a lot of blacklist checks in filter_recipient.

There's a wiki page on how to use spamc from within mimedefang. I'm
sortof working on a replacement spam_assassin_check based on
Mail::SpamAssassin::Client, to make it more efficient, but it's not
ready yet I'm afraid.
