Makes sense, but I was thinking you meant "by order of importance" not
"by order of precedence.". It is kind of interesting that there may be
a way for e-mail that is scanned and contains a virus could run code on
the system? Anyone have some background in this? I am not sure how that
would work and am not sure it is even possible since Spamassassin
basically is doing a regex on text and skips messages larger than a
certain size. At any rate, we block viruses before before Spamassassin
come in and does its work.

My other point was to let spamassassin do BL checks also. So I would
thinking .
1) DNSBL checks
2) Virus checks
3) Spam checks ( including DNSBL )
