I've had good experience with DSBL (www.dsbl.org). Seems to catch a lot of open-whatever. -- Juha Saarinen
This morning I did a check on my mail server logs over the past 7 days.
Here's the number of messages rejected by each respective RBL I use :
8 relays.ordb.org
258 bl.spamcop.net
0 opm.blitzed.org
0 proxies.relays.monkeys.com
23 sbl.spamhaus.org
11 Relays.OsiruSoft.com
0 blackhole.ElectroCity.com
Listed in order checked by MTA, ie. I think sbl.spamhaus.org would catch
more
messages if it were checked before bl.spamcop.net. This is my personal mail
server - I don't recommend using spamcop's blacklist if you're an ISP.

You may wish to review your use of spamcop. Theres quite a few articles around on spamcop's practices which are questionable at best. I certainly won't use spamcop for our users, its too high risk of blocking valid SMTP servers. Its far too easy for any luser to get anyone blacklisted on spamcop. However, on the subject of blocking spam I've never found any combination of RBL's to make any significant difference. SpamAssassin+Razor on the other hand, its just amazing. -- Nigel Bovey Network Engineer Snap Internet Limited Well done pinky, that was almost coherent - The Brain.

Osirusoft is under a DDoS attack, apparently, so that one is down. -- Juha Saarinen

Agreed, Any luser on the net can get you listed on spamcop, its happened to us a few times due simply to spam that forged its from address to addresses under our domain. On the other hand, at least they notify you and its easy to get de-listed again, but still.... I wouldn't suggest spamcop for anything except personal use. The above stats also only show you how many *connections* were rejected too, not how many messages were rejected, also you have no idea how many of those messages were falsely rejected...(probably a lot with spamcop)

Yep, the days of outright blocking using RBL's have been and gone IMHO, they're just not a viable method anymore, more akin to cracking a nut with a sledgehammer. As extra points in a SpamAssassin score however, they work great... Regards, Simon
