No one in their right mind would block using BLARS, SPEWS, or the FIVETEN*
block lists, at least not in a commercial setting where receiving email
consistantly is important. You could certainly use them as part of a scoring
system like Spamassassin. And on a private email server, well, you can block
the whole world and it wouldn't matter, the only person losing email is
yourself.

Spamhaus tends to be rather good, and their XBL/CBL block list is quite
effective. Not many false positives, and collateral damage tends to be kept
to a minimum. So it is good for commerical/work settings.

Even the generally effective Spamcop should really only be used in a scoring
system, not outright blocking, because we've seen cases where IPs are
reported by just 1 or 2 users and already it causes that IP to be blocked,
so sometimes it doesn't take much for a relatively high volume ISP email
server to get blocked accidentally by people reporting spam. I think they
change their algorithms every now and then, so maybe they have changed the
above behaviour recently.

I like using actively maintained lists, rather than ones that tend to get
stale quite quickly... and ones that aren't anal and say you need to
"donate" $50, $100, $1000 to them to remove a listing, especially ones that
want to charge you even if THEY made the mistake! I've never been in any of
these "charge you" lists, but i can imagine that if you were in one, what
kind of hell you'd have to get out.

I inherited some IP space listed at five-ten and blars, but nowhere
else. Anyone using them?

Nope, but i had some problems with Blars at my last job. Generally, sending
the blocking admin a link to Blars home page (http://www.blars.org/blars.html
and http://www.blars.org/errors/block.html) would make them stop using that
list. Check out his photo I can't belive there is any serious admin who
would continue to use his list after reading what he charges to get you
delisted, or his criteria for blocking. I'm not even sure he's for real...

I'm not really informed about the other ones, but a quick check on fiveten and
spews make them look really bad for general use. Why can't people actually
read the conditions of blacklists before using them?

Hello,

Would you recommend using SPEWS Level1 (www.spews.org) for webhosting
company (offering also email service)? It is using l1.spews.dnsbl.sorbs.net,
although it is not mentioned on the sorbs website (only on spews.org). And
what about other sorbs lists? For example the "smtp" and "spam" lists.

Thanks

Hi,

Well, my fault... I was aware of that big discussion about de-listing fee,
but I just didn't realized that it was sorbs... So my question is now that
if it can be trusted for the SPEWS list... And if that list is not too
restrictive to use at smtp level for webhosting company...
