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.
I am thankful any help or suggestion for anti-spam and anti-malware.
you can use several blacklists or header/body checks to block spam or
malware to save your ressources. Another useful feature is the
upcoming Postfix server "postscreen" - this feature will be available
in Postfix 2.8.
Info: http://www.postfix.org/POSTSCREEN_README.html
Some header checks and maybe zen.spamhaus.org should block 85-95% of
spam. All other messages can be scanned with
spamassassin/amavisd/clamav or other commercial products.
To block malware you could also look at: http://www.malwarepatrol.net/
Start with some good Postfix restrictions and then you can extend your
setup with other filters/blacklists...
