My question is, how does BMTS detect spam. If it uses spamassassin, allows
users configure their preferences and SA uses them, user could apparently
whitelist debian lists so mail from them wouldn't be rejected.
(this might be question to spamassassin-users list)

I've seen it already happen, that spammer subscribed debian mailing list to
send spam there. Since debian list policy recommends its members not to
reject mail from it (quite correct I'd say, I did whitelist them), it may be
interesting for spammers to spam through them

It depends on the way BMTS uses surbl...
