Hi, I'm managing several mail servers running CentOS 7, Postfix and Dovecot. SpamAssassin is filtering mail nicely, but I'm considering using RBL (blacklists) to take some load off the servers. General question to those of you who use RBL. Which lists do you recommend using?

I realize this is slightly off topic, but I've noticed recently that I've been unable to preform RBL lookups using the the zen and sbl spamhaus RBL lists. Currently using Zimbra Collaboration Suite using CentOS 5 I'm seeing logs showing the following output. [root at phantom ~]# cat /var/log/zimbra.log | grep spamhaus Jul 18 13:07:12 phantom postfix/smtpd[27001]: warning: 107.178.203.192.zen....

Dear Friend, I done configuration using RBLSMTPD with WHITELIST, but I don't know it is correct. Please check files below are corrects.

...p/chktst.log # return OK exit 0 # return FAIL exit 1 END I get the log entry: ip=127.0.0.1 service=imap /usr/local/dovecot-2.2.15/libexec/dovecot/checkpassword-reply and with exit 0, the next passdb{} let me login, and with exit 1, all logins fail. So, with the current stock Dovecot you can make RBL calls and decissions with a script. ;-) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQEVAwUBVPjOlXz1H7kL/d9rAQIDFggAtDGl8rgN3zpOa8QQ1JVgVne5alAzBShN JfWm/4rDLBqPfAeqLX8OGUja19dxru0rJFAZPr673v7I4GfGVu2XHgEFV7qWag/m r32B//ADgvyBc0hwYOy2IQ4Zc2BW7K7Xx9hvbA5ZzmlD...

This was brought up in 2014, and left without conclusion, so I thought it would be time to bump it :) I would love a way to do allow_nets based on an RBL check, could this be added to the feature-list? https://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets Thanks -- Tom

Hi i want to fetchmail from a pop server and check every email to any rbl spamhaus,spamcop,etc and if match at any rbl the email will be deleted. It's possible to do this? Thanks Nightduke

I would like to have a list of IPs (hacker list) that I can do a lookup on so that if anyone tries to authenticate to dovecot they always fail if they are on my list. I have the list - and the list is available as a DNS blacklist. I'd like to have it work with both local IP lists or RBL lookup. The idea is so hackers from known IP addresses never succeed. If Dovecot provides the feature I have about 1/2 million IP addresses of known current hackers to block. Anyone else interested in this?

Hai Alex, I use the same as in the link you posted. http://rob0.nodns4.us/postscreen.html This is used for my bases setup also. Just put all your servers (rbls) in here and copy the response lines, Like : /^zen\.spamhaus\.org$/ blocked by rbl, see http://multirbl.valli.org /^bl\.spameatingmonkey\.net$/ blocked by rbl, see http://multirbl.valli.org /^b\.barracudacentral\.org$/ blocked by rbl, see http://multirbl.valli.org And you see postfix/postscree...

I just read about the webpage http://www.summersault.com/chris/techno/qmail/qmail-antispam.html on the qmail list. This makes it possible to use RBL on a per user basis. Perhaps somebody can adopt this for Postfix and mailman---or whatever is used to manage this list? Mate

In case someone's using the nixspam RBL and wondering why the influx from the CentOS mailing lists has stopped today: http://www.dnsbl.manitu.net/lookup.php?language=en&value=72.21.40.12 Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

No idea where else to ask this and get a real qualified answer but here. Not exactly pure centos question....but... I am adding blacklists to my postfix smtpd settings. I have the inkling that after the first lookup for a domain or ip that my dns caches the result and I no longer bother the RBL or RHSBL list owners anymore in that instance. Is that correct? I hate to waste their resources if it is not. thanks, bob
