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

Hi, I have a working installation of Postfix and Dovecot that works nicely. I've added SpamAssassin, which does a good job of flagging spam. Now I wanted to add greylisting to my server. Here's what I did. $ sudo yum install postgrey Increase the greylisting delay. # /etc/sysconfig/postgrey POSTGREY_OPTS="--delay=300" Edit /etc/postfix/main.cf accordingly.

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

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?

I know it is not dovecot who should fix this. But anyone using dovecot is using an MTA, and receiving spam ;) I know how to look at email headers.

Hello: On a CentOS5 machine I set up for a client, in /etc/aliases, I set root's mail to forward to my email address so I can get notices from cron, etc. Unfortunately, I am now getting a lot of spam which is sent to root at theservername.com How can I tell sendmail to not accept external email to root? I searched the Internet and found some horribly convoluted solutions. There has to

Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more

I wish to add options to sendmail INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass-milter/spamass-milter.sock, F=T, T=C:5m;S:4m;R:4m;E:5m')dnl dnl MAILER(cyrusv2)dnl INPUT_MAIL_FILTER(`greylist', `S=local:/var/run/milter-greylist/milter-greylist.sock') define(`confMILTER_MACROS_CONNECT', `j, {if_addr}') define(`confMILTER_MACROS_HELO', `{verify},

Hi All, I'm just wanting to check that my understanding of the settings is correct as my web searches are finding a lot of dated information.

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
