1.	Install RAV AntiVirus v8 for Postfix
= 	====================================
	The product contains the following packages:
	ravcore-8.*.tgz		-- RAV scanning engine
	ravmd-8.*.tgz		-- RAV mail scanning daemon
	ravpostfix-8.*.tgz	-- RAV smtp server used by postfix

	You can use our install.sh script in order to install them or use the
	following comands to install them manually (you must be root):

	pkg_add ravcore-*
	in order to install ravcore.

	pkg_add ravmd-*
	in order to install ravmd.

	pkg_add ravpostfix-*
	in order to install ravpostfix.

2.	Start the RAV daemons (ravmd and ravpostfix)
=	============================================
	The ravpostfix daemon starts with:	
	/usr/local/etc/rc.d/rpostfix.sh start
	or
	/usr/local/bin/ravpostfix -s 10025 -c 10026

	The installation process will try to add automatically in the
	file /usr/local/etc/rav/domains two values for the 'domain'
	parameter (the hostname and the domainname for the local machine).
	Please verify if the values are correctly specified. If the
	domain values are successfully added then the ravmd daemon 
	will be started when the installation has been finished.

	You can manually start the ravmd daemon using:
	/usr/local/etc/rc.d/ravmail.sh start
	or
	/usr/local/bin/ravmd

	By default, ravmd will use RAV logging system. The log files 
	are located in the /var/rav/log/ directory.
	If '--syslog' is used in the ravmd command line parameters, 
	ravmd will use syslogd daemon for logging. Please check mail info
	log file to see ravmd's output.

	IMPORTANT: For RAV, a 'domain' is the string which follows the '@'
	symbol in an e-mail address.

	Section 6 from the README file contains more information about
	starting/stopping the daemons.

3.	Modify postfix configuration
=	============================
	If the postfix configuration files are installed in the 
	/etc/postfix directory then the installation process will 
	add the RAV settings in the main.cf and master.cf files.

	Otherwise you must configure the Postfix system to allow
	content filtering as described in FILTER_README file from
	the Postfix distribution.

	Add next line in /etc/postfix/main.cf:
	content_filter = smtp:[127.0.0.1]:10025

	Add next two lines in /etc/postfix/master.cf:
	127.0.0.1:10026		inet n - n - 100 smtpd
			-o content_filter= -o myhostname=dummy.domain.name

	DO NOT use your FQDN instead of 'dummy.domain.name' because in some
	configurations postfix will bounce the mail with this error:
	status=bounced (mail for 127.0.0.1:10025 loops back to myself).

	If, after you have installed RAV, postfix is complaining about a 
	relaying issue (Relay access denied) then you have to configure it
	to accept localhost as a relay. Just add this entry in the main.cf file:
	mynetworks = other_networks, 127.0.0.0/8

	For more information please read "Advanced content filtering" section 
	from FILTER_README.

4.	Restart postfix system
=	======================

	postfix reload
