+This software requires Sendmail tobe compiled with mail filter support.
+So be sure you have the following in your /etc/make.conf:
+
+SENDMAIL_CFLAGS+= -D_FFR_MILTER=1
+
+in order to have Sendmail always compiled with mail filtering support when you
+build your system from sources. If Sendmail is not yet recompiled with this
+flag, then do the following:
+
+cd /usr/src/usr.sbin/sendmail
+make clean
