I also found it a good practice to pass only small messages (<512KB)
to SpamAssassin. Spam mail is usually quite small and thus this
setting saves processing time and memory, especially if your users are
prone to send large files via mail.
# send all messages < 512KB through spamassassin
if ($SIZE < 524288)
{
exception {
xfilter "/usr/bin/spamc"
}
}
