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 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]

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

I'm trying to put an end to the spam at least and the built-in stuff for Evolution isn't working as well as it should I did some Googling on procmail and fetchmail and spamassassin config files and much

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,

Running CentOS 4.2 with all updates. I've been using sendmail for my MTA since forever. I've grown used to it and I can make it do what I want it to. However (there's always a catch, isn't there)... Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to

Hi everybody, I am trying to work with quota. I use postfix and dovecot with a sql backend. Below you'll find my configuration. Everything works except for the quota part.

Hi, Since upgrading our mail servers to Postfix/Dovecot, we've seen a rather large increase in botnet brute force password attacks. I guess our old servers were too slow to suit their needs. Now, when they hit upon a valid user, it's easy to see what passwords they are trying (we've enabled auth_debug_passwords and set auth_verbose_passwords = plain). We can easily have log

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

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 :
