similar to: Fetchmail pop server and clean spam messages

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 :

Gents, I have added the following to /etc/mail/sendmail.mc and rebuilt it trying to control spam. I still get about 25 spam messages a day. Is there something else that can help control spam?

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

I have enabled the feature in sendmail.mc to check with spamhaus for spammers. However since this block is being made at MTA level, I would like to know is something can be done to obtain statistics of blocked attemps. thanks -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama,

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

Dear All, its a offtopic question but really apprecite if someone would advise n help i have been running a mil server with sendmail and have sbl-xbl.spamhaus.org as my dnsbl. i had other servers which are alredy out now that is relays.ordb.org and dsbl.org have already been out of my sendmail config. any one knows of ny other servers i could add in my sendmail config apprecite ur help

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:

Hi all, Just out of curiosity: is there anything we can do, on the samba side, to counter the recent ransomware attacks? (or limit the damage done) I'm thinking like: limit the number of files per second a client (workstation) is allowed to edit, or some other smart tricks..? It would be nice if samba could be an extra layer of defense. Something perhaps a vfs module could help with..?

Hi, I'm not sure what the policy of this list is and I bet everyone has a spam filter, so nobody might have noticed, but we got spammed. Can anyone send mail to the list or do you have to subscribe first ? -- dag wieers, dag@wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power]

Smtp1.song.fi and smtp2.song.fi, our list servers, seem to have gotten listed in the bl.spamcop.net RBL. Spamcop listings are temporary and will time out, and because of occasional major false positives (or perhaps collateral damage?) like this I don't use it to reject mail. Anyone who IS using Spamcop to reject mail has missed much of today's list traffic. -- mail to this

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

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?

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

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
