+====== Setup clamav with Postfix on Debian Lenny in a chroot ======
+Quick and dirty instructions on setting up Postfix to scan messages using clamav on Debian Lenny.
+Install clamav and clamav-milter:
+<code>
+apt-get install clamav
+apt-get install clamav-daemon
+apt-get install clamav-milter
+</code>
+Edit /etc/default/clamav-milter and uncomment the following lines
+<code>
+USE_POSTFIX='yes'
+SOCKET=local:/var/spool/postfix/clamav/clamav-milter.ctl
+</code>
+If you don't want the postmaster and sender to be emailed each time a virus is detected then add the letter q to the OPTIONS line at the beginning of the file as such:
+<code>
+OPTIONS="--max-children=2 -olq"
+</code>
+Create somewhere within the Postfix chroot for the clamav-milter socket to sit. The default location cannot be seen by Postfix when it is in a chroot jail.
+<code>
+mkdir -p /var/spool/postfix/clamav/
+chown clamav:postfix /var/spool/postfix/clamav/
+chmod g+s /var/spool/postfix/clamav/
+</code>
+Restart the milter:
+<code>
+/etc/init.d/clamav-milter restart
+</code>
+Add the following lines to /etc/postfix/main.cf to enable the milter (assumes you want to accept emails on milter failure):
+<code>
+milter_connect_macros = i b j _ {daemon_name} {if_name} {if_addr}
+smtpd_milters = unix:/clamav/clamav-milter.ctl
+milter_default_action = accept
+</code>
+Restart Postfix:
+<code>
+/etc/init.d/postfix restart
+</code>
