[gentoo-user] Greylisting vs. reject_rbl_client

[Grant]

I've followed the steps outlined here to eliminate spam up to the
section on "SPF and greylisting" on the second page:

http://www.freesoftwaremagazine.com/articles/focus_spam_postfix/

The author is really into greylisting:

"If you take nothing else from this article, let it be that
greylisting is a Good Thing and your customers will love you for using
it"

but the feedback I got on it from this list was not as positive.  Of
the stuff I've implemented, these lines seem to have been the most
effective:

reject_rbl_client relays.ordb.org,
reject_rbl_client list.dsbl.org,
reject_rbl_client sbl-xbl.spamhaus.org,

with the spamhaus.org line doing most of the work according to the logs.

Do you think the reject_rbl_client stuff is safer than greylisting?
