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?

Hello people, I am using now qmail in cluster with LDAP + Interscan Messaging Security Suite from Trendmicro. I need to develop a new solution with: - postfix - dovecot - anti-spam - anti-malware.

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. 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

So I did a fresh install today. Decided to go ahead and upgrade. Everything seems okay save for three problems. #1 - I get a message during boot saying that an Intel microcode update didn't work. Something about not being able to find /proc/microcode. #2 - I can't use the Firefox extension HTML Parser. Anyone use this. #3 - Off and on GDM crashes and I get dropped into a prompt. Any

Dear CentOS Community Is totally clear there's no support sendmail platform today, but I need to stop SMTP brute-force attack on sendmail. My server is attacked today, my maillog look like : 4624 at myserver.com>, proto=ESMTP, daemon=MTA, relay=myserver.com [127.0.0.1] Jun 14 19:07:01 at6412 sendmail[24627]: q5EN71jC024627: from=<>, size=3958, class=0, nrcpts=1,

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]

Recently, I added the below line to my sendmail.mc and rebuilt. Everything was working just fine until sometime today. In looking over the maillog, it seems if almost every piece of mail was rejected because of this configuration - mail that I know is OK, valid, and not a source of spam, like tamu.edu. Not only that, but the mailing list from centos was being rejected as well. Anyone know

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. It doesn't seem to see the quota and doesn't respond to the sender that the client is over its quota. versions: postfix-2.5.20070531-mysql dovecot-1.0.2-mysql Thanks for the help in advance.

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

Since upgrading to 2.3.0 / 0.5.0.1, incoming PDFs are getting mangled. It seems to be happening when I use vnd.dovecot.filter. When I comment out the block, things come through fine. My filter block looks like this: require "vnd.dovecot.filter"; filter "bogofilter_filter"; if header :contains "X-Bogosity" [ "Spam,

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,

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, on my small Xen-virtualised server with 48 MiB RAM I use Postfix and Dovecot, because the Debian administrators dislike qmail [1], which is in my opinion despite some maintainability and code quality issues a quite well designed software, because it mostly follows the UNIX principles. Postfix is not able to sort my E-Mail into different Maildir folders and after I looked at procmail's

I'm using maildrop to filter mail like: xfilter "/usr/bin/spamc" xfilter "/usr/bin/bogofilter -ep" I want to change to deliver (so I can use sieve) but can deliver do this?
