clamav-milter

Nigel Horne's clamav-milter is a very fast email scanner designed for Sendmail. It's written entirely in C and only depends on clamd. You can find detailed installation instructions in the INSTALL file that comes with the clamav-milter sources. Basically, to connect it with Sendmail add the following lines to /etc/mail/sendmail.mc:

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

Check entry in clamd.conf of the form:

	LocalSocket /var/run/clamd.sock

Start clamav-milter

	/usr/local/sbin/clamav-milter -lo /var/run/clmilter.sock

and restart sendmail.
