Yes, you are right.

Yep, yep and yep.

Well I am running Spamassassin anyway, although I haven't upgraded to
FC3 (and hence Spamassassin 3.0) yet (still waiting for Fedora Extras).
I am looking forward to upgrading to Spamassassin 3.0 as quite a few
spam messages are getting through now, even with Bayesian filtering.
Blacklists were appealing because I was hoping I could get Postfix to
reject some messages before they even got to Spamassassin, but as my
Postfix isn't really working like a proper mail server and just does
local delivery and relaying to my ISP's SMTP server I guess there isn't
much more I can do.

Thanks.

Best, Darren
