Please read documentation on http://www.amavis.org/ before you start using it.

  To configure postfix, you have to do later:

  * add

    content_filter = vscan:

    to /usr/local/etc/postfix/main.cf

  * add

    vscan  unix	-	n	n	-	10	pipe	user=vscan
	argv=/usr/local/sbin/amavis ${sender} ${recipient}
    localhost:10025 inet n -	n	-	-	smtpd
	-o content_filter=

    to /etc/postfix/master.cf.
