Setting up clamav-milter on Gentoo Linux


Step 1 - Configure clamd

	mv /etc/clamav.conf /etc/clamav.conf.dist
	nano -w /etc/clamav.conf

	# This is my /etc/clamav.conf
	LogFile /tmp/clamd.log
	LogFileMaxSize 16M
	LogTime
	LogSyslog
	PidFile /var/run/clamd.pid
	DataDirectory /usr/share/clamav
	LocalSocket /var/run/clamd.sock
	StreamSaveToDisk
	MaxDirectoryRecursion 15
	ScanMail
	ScanArchive
	ArchiveMaxFileSize 10M
	ArchiveMaxRecursion 5
	ArchiveMaxFiles 1000

Step 2 - Tell the init script to start clamd as well as freshclam

	nano -w /etc/conf.d/clamd

	START_CLAMD=yes

Step 3 - Start clamd

	/etc/init.d/clamd start

Step 4 - Edit sendmail.mc

	Add these lines to sendmail.mc before any any other 
	INPUT_MAIL_FILTER lines and before MAILER(local)
	NOTE: ANY INPUT_MAIL_FILTER definitions put before these lines
	will be discarded due to the use of confINPUT_MAIL_FILTERS
	Make this your first mail filter. :)

	INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clmilter.sock, F=, T=S:4m;R:4m')dnl
	define(`confINPUT_MAIL_FILTERS', `clmilter')dnl

Step 5 - Rebuild sendmail.cf

	cd /etc/mail
	m4 sendmail.mc > sendmail.cf

Step 6 - Start clamav-milter

	/usr/sbin/clamav-milter -blo /var/run/clmilter.sock

Step 7 - Restart sendmail

	/etc/init.d/sendmail restart
