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

I have a problem getting spamd and sendmail (both stock CentOS4 rpms) to work together on a couple of smtp relay machines. This is clearly a configuration issue and no doubt revolves around my lack of comprehension of how this is to work. Basically, the setup consists of two frontend public smtp transports that redirect all email through a firewall to an internal imap server for final

What makes Postfix superior in fighting spam? How do I integrate MIMEDefang, SpamAssassin, and ClamAV with Postfix? Are there migration guides for moving one's Sendmail anti-spam and AV

Hi Folks, I have a couple of questions which I hope that you will be able to assist with, first some background. I run a few sendmail servers that run MailScanner/Spamassassin/sendmail (current versions) on Centos 5.4 and Centos 4.8 These boxes accept mail for a large number of domains (6000+) scan the mail removing spam and then forward the ham to another server for delivery. I am attempting to

I was wondering what were some of the best guides on the web for Postfix (Maildir), Spamassassin, ClamAV, Dovecot? In the list I miss a program to control clamav and spamassassin. Many people use amavis, but my experience is not very favoufable with this script. I

Hello all, I've been trying to get spamassassin and clamav working, but got really confused when I realized there are various incarnations of the software. Originally, I started out with just spamassassin, but learned there is also an SA-milter. Can someone tell me which of the various spam fighting packages i.e., sa, sa-milter, clamav, clamave-milter, and so forth? I ran into

I only have one Postfix server running at the moment and have some questions. On that install, I did Amavisd-new with ClamAV, SpamAssassin, Postfix and Dovecot. I know this is a bit off topic, but I'm really hoping for performance guidance. Is the added layer of complexity running Amavis worth the effort on a system with moderate mail flow? Or should I just go down the path of getting

I have just followed Johnny Hughes' excellent walk-through on how to install Postfix, MailScanner with ClamAV and Spamassassin and it seems to be running fine during in house testing, but I want to make sure that it behaves itself when it goes live serving about 250 users; I have read comments elsewhere both for and against the use of Mailscanner with Postfix, and when I mentioned the subject

Hi, I'm looking for a way, in sendmail, to set access rule, saying: Accept messages for domain.com only from this IP address. I did some research yesterday, but could only find a way to restrict by IP for all domains managed by sendmail. Any ideas? Regards, Ugo

Whats a good antispam solution? I am using sendmail and dovecot 1.1. I came across dovecot's antispam plugin, but it seems it does not support 1.1 yet. I am also looking for something non-perl based. I am already doing some greylisting with sendmail milter. Any other good suggestions? If not, I guess I might have to downgrade back to 1.0 dovecot. Thanks

Someone got ahold of my information (actually, I know who they are - t2net.net - just not how to get back at them) and now I'm getting 4 phone calls a week upwards of 20 spams a day. 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

Sorry, not a direct CentOS question, but I know there's a lot of experienced users on this list...I'm using CentOS with sendmail and spamassassin. I've got it configured with spamass-milter and it is working correctly. However, I was expecting to be able to reject mail that is marked as spam, not just deliver it as usual. Anyone know if it can be done and how? I know a milter

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

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?

New be in linux! Currently I have Install DNS, Email and Web server using centos 4.3. All functions are running properly! What anti virus and anti spam recomended for me to install to my server? What I have to configure after installing anti virus and anti spam? Would some one help me please.! Now many spam mail come to user mailbox! Thank's 'n Regards Horasima

I tried to google, but find no directions for configuring this. I would like to 1) limit greylisting only for messages that come from other countries 2) give higher spam level to these messages (preferably only for certain receiving email addresses) I already have installed geoip.x86_64 (1.4.6-1.el5.rf). How to proceed? Or should I move to CentOS 6 for this? - Jussi
