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?

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 :

I have had the same email address since 1997 (when microsoft stole bob.com from me thanks to network solutions...) In the early days I of course was free with my email and used it everwhere. Fast forward to 2012, some 15 years later. woof..the amount of spam sent to me has always just kept getting worse and worse. On my centos 5 server I just used sendmail with spamassassin and it killed a

Hi list, I have noted over the last week or so my DNS servers are dumping lots of messages for bogus domain lookups. Examining the postfix queue with postqueue -p: I see many (Host or domain name not found.

Recently we began seeing lots of these log entries on our off-site mx smtp host. I have googled this but I am not clear from what I have read if this is something we can stop altogether or should even worry about. Comments?

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

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, 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]

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..?
