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?

Okay, Yahoo is bumming me. Only system my mail is having an issue with. All mail is accepted, but junked. I can only think it is the DKIM/Domain keys. It is apparent that the dkim-milter is not part of the centos 5.x distro nor is it part of the mirrors, as far as I can tell. So...have any of you done it with your servers for sendmail? There are some sites that claim to have rpms and I have

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

Hi, Is it possible to get Shorewall to reload the static blacklist file without resetting the packet and byte counters? I am following the guide at http://mudy.wordpress.com/2009/02/21/shorewall-blacklist-spamhaus-dshield/ to periodically generate a blacklist, but "shorewall -qq refresh -n blacklst" resets all my accounting. Is there a way to do this without resetting the counters? I

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 :

Does anybody have a good method for disabling SA checks on outbound email under sendmail running the spamass milter? Some of our Vhost accounts are getting flagged as spam on the way out due to being on a dirty ISP network. John Hinton

Well, I stumbled onto zimbra.... I have a Scallix system built, but still have some rough edges to try to smooth. Like the way it works with sendmail, no dnsbl's will work as sendmail sees all mail as coming from locohost (scalix). Still battling that one which is when I ran across Zimbra. So, this made me start wondering. Are there other exchange server-like products out there? Has

what anti-spam for you used ? dspam?spammassian? amavisd-new ? what is best ?

Strangest thing. Since some time Marts 25. I'm no longer receiving mails from the dovecot mailing list server. Mails from other sources are behaving fine. Instead I'm just seing Mar 26 08:27:54 dna01 postfix/smtpd[107746]: Anonymous TLS connection established from talvi.dovecot.org[94.237.25.159]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 26 08:27:54 dna01

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

Perhaps someone can help me understand why this is happening. I''m trying to write a script using ''shorewall iprange'' to parse some ip ranges into subnets so that i can place them into the blocklist. I keep getting an error when i run the script though. Here is the script: #!/bin/csh foreach i (`cat ipranges`) shorewall iprange $i >>

Hah!!! This list is just too calm and mundane. The only thing we argue about is the ''announce'' list vs. the ''user'' list. ;) So, it''s springtime!

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..?

Hello all, About a year ago I set up a mail server on CentOS using this howto: http://wanderingbarque.com/howtos/mailserver/mailserver.html I managed to add amavisd-new with clamav and spamassassin. It runs very well, but it runs on CentOS 5.2, and if I try to upgrade, amavisd-new and clamav break. we are now also at the point where a backup mx will need to be implemented. If necessary I am
