Making SA lightweight seems to be a futile job. Would require a large
revamp of code, as even with little or no rulesets, it still takes
dozens megabytes worth of RAM. Not to even mention that things like MIME
decoding would be done twice OOTB.

Slightly offtopic: it's bad that no alternative to SA (preferably
written in C) exists, it seems not to do much more than DNSBL checks,
MIME decoding, HTML parsing and regexp matching. Even with that, on a
pretty minimalistic setup, the daemon occupies 110MB of memory. Perl
seems to show its weight. I hope I'll have enough persistence to create
something similar, but without that much of a memory footprint.
