Hey Ned, I found this very useful to test that the RBL was working: http://www.spamhaus.org/faq/answers.lasso?section=Spamhaus%20SBL#207 " How do I test my SBL setup? Once you have set up your mail server to use sbl.spamhaus.org (or the preferred zen.spamhaus.org), you can test to see if the SBL blocking is working by sending an email (any email) to: nelson-sbl-test at crynwr.com

All; I installed sendmail via yum, but if I test it like this: echo "Subject: sendmail test" | sendmail sbob at quadratum-braccas.com I get a local mail on the server with this every time: Message? 1: From MAILER-DAEMON at kdb-bugs.example.com?

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 :

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

Hi, I'm currently fine-tuning my mail server (Postfix and Dovecot on CentOS 7). SPF, DKIM and DMARC work fine, now I'd like to limit the spam tsunami. Besides the official Postfix documentation, I've read a few articles about Postfix spam restrictions, namely these : https://www.linuxbabe.com/mail-server/block-email-spam-postfix https://wiki.centos.org/HowTos/postfix_restrictions

I've been running sendmail since the beginning of my online time. 1. Did I see that postfix can run sendmail milters? 2. If so, did I read that postfix can run these separately for inbound vs. outbound? 3. Can it run like a rbl blacklist on inbound and not outbound? 4. If the above is true, does this require separate configurations of postfix or is it already set to allow this out of the

Postfix provides the

I've recently switched to using spamassassin via a sendmail milter, rather than using procmail to invoke it. This means that I get a number of messages appearing in my maillog, and then being reported by logwatch as unmatched entries. An example of such a messages is: Feb 27 04:33:09 quail sendmail[24780]: p1R4X46P024780[2]: URIBL blacklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5

In the past I've used a combination of spamhaus combined RBL's and Spamassassin with Mailscanner as my spam recipe, but this stopped working very well for me well over a year ago. As many of the users of the couple small/personal mail servers I run are NOT technical people, and use POP to read their mail, 'training' spamassassin is difficult at best. Once upon a time, using
