Can anyone provide me the full, latest and updated blacklist Ip of spam servers?
I would suggest you do whois.sc/IPHERE - put your ip there, and it will tell you if that ip is blacklisted.
Thanks Intech.
I use SpamAssain.
Would I need the configure Spam Assain?
Is the list of 'black list IP s' is updated automatically?
Can anyone share their experience?
My experience is that blocking IPs won't stop spam, and will only serve to punish legitimate emailers that may also reside on those servers. Spammers move from IP to IP constantly.
so is there really any way to stop spam?
If there were, this thread wouldn't need to exist.Quote:

RBLs (Real-time blacklists) below will give you by far the most accurate and up-to-date information about spamming IPs:
dnsbl.njabl.org
list.dsbl.org
dnsbl.sorbs.net
sbl.spamhaus.org
opm.blitzed.org
bl.spamcop.net
dynablock.njabl.org
cbl.abuseat.org
For manual checks I would recommend http://www.senderbase.org . It will provide search results from all major RBLs, google groups and SpamCop.
Absolutely. Time has proven them to be tremendously effective.Quote:

Very close to what we're running with the exception of spamcop (high rate of false positives) and sorbs. We were running sorbs minus the pay-to-delist 'spam.dnsbl.sorbs.net' zone, but dropped them completely just a couple of days ago as an audit showed that 100% of what sorbs was catching was already covered by other lists.Quote:
dnsbl.njabl.org
list.dsbl.org
dnsbl.sorbs.net
sbl.spamhaus.org
opm.blitzed.org
bl.spamcop.net
dynablock.njabl.org
cbl.abuseat.org
We may use the occasional blackholes.us list as well depending on the server and/or a particular client's wishes, and also use bondedsender to help cut down on what could be considered false positives by some.
I'm a little taken aback that there are still people who would assert that dnsbls in general are ineffective, given all the evidence to the contrary. All it really takes is careful selection and a watchful eye.

Spam blacklists are a horrible way to combat spam. Many legitimate emails WILL be lost. Make sure you let your customers know that you are censoring their email if you use one.

I think it's rather disingenuous of you to attempt to paint all DNSBLs with such a broad brush. You've been around long enough to know that there are some publicly available DNSBL such as Spamhaus and the CBL that are balls-on accurate, widely used, highly respected, and very, very effective. The credibility of outfits like Spamhaus is no accident, and frankly, pretty much indisputable at this point..Quote:

My opinion, based on first-hand experience as well as anecdotal evidence, is that those who experience an unacceptably high rate of false positives (say, over 1% or so) have not bothered to match their choice of DNSBL to the type of traffic hitting their machines or to the needs of their customers. You can't just indiscriminately slap a handful of DNSBLs into your MTA config and expect miracles to happen. Sadly, this is exactly what many inexperienced admins do.
Everyone knows that there lists out there that are pure crap, hence my "careful selection and watchful eye" comment in a previous post. Again, it is up to the individual server admin to determine which is which and then choose accordingly based on his or her own needs.
Censorship would imply rejection based on content. DNSBLs block based on source/source history history. That said, I agree that anyone downstream of any type of spam filtering scheme should be made aware of said filtering.Quote:
