As well as as some for the amavisd-new daemon itself. To allow amavisd-new to send them back to postfix, we need to add additional configuration. The above configuration will send the emails to amavisd-new. Add a line with “-o content_filter=smtp-amavis::10024” directly underneath it.

They include Postgrey policy server implementing greylisting, amavisd-new as a wrapper between postfix and other components like Spamassasin as the spam filter, ClamAV as the virus scanner, and SPF and DKIM libraries. The following commands will install the required components for this setup. After the emails are checked, they are sent back to postfix for delivery. There, the emails get checked for viruses and spam. In the setup described in this post, postfix passes incoming mail on to amavisd-new.
