[TOC]
In iRedMail, Amavisd provides below features:
- content-based spam scanning (invoke SpamAssassin)
- Virus scanning (invoke ClamAV)
- DKIM signing
- DKIM verification (through SpamAssassin + Perl module)
- SPF verification (through SpamAssassin + Perl module)
- Disclaimer (throught AlterMIME)
Stop virus/spam scanning, keep DKIM signing/verification and Disclaimer
If you want to disable virus and spam scanning, but keep DKIM signing and disclaimer, please try this:
-
Keep
content_filter = smtp-amavis:[127.0.0.1]:10024
in Postfix config file/etc/postfix/main.cf
. -
Find below lines in Amavisd config file:
- On RHEL/CentOS, it's
/etc/amavisd/amavisd.conf
- On Debian/Ubuntu, it's
/etc/amavis/conf.d/50-user
- On FreeBSD, it's
/usr/local/etc/amavisd.conf
- On OpenBSD, it's
/etc/amavisd.conf
- On RHEL/CentOS, it's
# @bypass_virus_checks_maps = (1); # controls running of anti-virus code
# @bypass_spam_checks_maps = (1); # controls running of anti-spam code
Uncomment above lines (removing "# " at the beginning of each line), and restart Amavisd service.
Completely disable all features
If you want to completely disable spam and virus scanning services, steps:
- Comment out below two lines in Postfix config file
/etc/postfix/main.cf
:
content_filter = smtp-amavis:[127.0.0.1]:10024
receive_override_options = no_address_mappings # <- it's ok if you don't have this line
- Comment out below line in Postfix config file
/etc/postfix/master.cf
,
-o content_filter=smtp-amavis:[127.0.0.1]:10026
- Restarting Postfix service is required.
- Disable network services: Amavisd, ClamAV.
Notes:
- ClamAV and SpamAssassin will be invoked by Amavisd, so if you disable Amavisd, those two are disabled too.
- SpamAssassin doesn't have daemon service running in iRedMail solution, so there's no need to stop SpamAssassin service.
