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? Cheers, Niki -- Microlinux - Solutions informatiques durables 7, place de l'?glise - 30730 Montpezat Site :

Hello, I have a question about postfix. I have a few webservers, each with their own mailing system. Obviously manually adding items can be quite tedious going from one to another to another. I am in the process of making a list of domains (commercial spammers) that bother me. My idea is to use the access file to reject them. My question is this... Can I make a text page on one of my html

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

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

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication.

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters). I have an issue with auto-replies - it is vulnerable to spamming with forged email address. Forging can be prevented with several Postfix settings, which I did in the past - but was forced

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

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

after having my own dnsbl feeded by a honeypot and even mod_security supports it for webservers i think dovecot sould support the same to prevent dictionary attacks from known bad hosts, in our case that blacklist is 100% trustable and blocks before SMTP-Auth while normal RBL's are after SASL i admit that i am not a C/C++-programmer, but i think doing the DNS request and in case it has a

hi all I've been reading this thread with interest. As a rather novice programmer. I'm not being humble here, I really am not very good, I can do stuff, but it takes a LONG time. My spaghetti code even has meatballs in it ! Not being a great programmer I'm not really able to code something up, but it occurred to me something could be scripted, are the other posters suggesting

My apologies if I'm posting the wrong place, or am asking a common question.
