sendmail milter support

[Spades]

hihi,

how do i check if my sendmail 8.12.11 has milter support compiled?
how should i install it via ports to have milter up?

also i could only find freebsd.mc file that was inside /etc/mail
that was *.mc and not sendmail.mc.

I edited freebsd.mc and added:
INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clamav/clmilter.sock, F=,
T=S:4m;R:4m')

i tried restarting sendmail process but it didn't take effect, so i need to
make and make install in /etc/mail. i did that and nothing happen.
