[Mimedefang] RBL's

[-ray]

I haven't used RBL's in the past because of the network latency in making
over 200k internet DNS queries per day.  However i recently got rsync
access to the spamhaus.org sbl and xbl lists, and have been maintaining a
local copy using rbldnsd.  I think the local DNS/network is fast enough to 
keep up.  Thoughts?

Are the spamhaus.org lists any good?  Any horror stories?  What about 
other's?  Lucas mentioned surbl.  I see i can get rsync access to surbl, 
which is good.  I may try it out.  Any others?

Also should i just use a sendmail dnsbl, or let Spamassassin do the dnsbl 
queries?  There are advantages and disadvantages either way.  Where in 
Spammassin can i disable all the public RBL's but only leave access to my 
local RBL?

Lastly any general thoughts on using RBL's?  I used to be very much 
against the use of RBL's... but the Spam coming through is already way out 
of hand.
