Honestly speaking I don't know how to start it. Maybe inetd starts it, 
maybe courier-imap or You might start it manually?! Unfortunately I dont 
have such problems You have without fam. But if You have found out 
please let me know, I'm interested. :)

If You take a look what the WITH_FAM macro actually does, You'll see it 
only adds fam as a dependency and adds some extra cc flags, but leave 
the CONFIGURE_ARGS untouched. Afaik fam can't be actually disabled in 
courier-imap.

.if defined(WITH_FAM) || exists(${LOCALBASE}/lib/libfam.so)
CONFIGURE_ENV=  CPPFLAGS="-I${LOCALBASE}/include" \
                LDFLAGS="${LDFLAGS}"
LDFLAGS+=       -L${LOCALBASE}/lib
LIB_DEPENDS+=   fam.0:${PORTSDIR}/devel/fam
.endif

Likely there is the libfam.so linked, as You can see above, but that is 
only a prerequisite to use famd. Famd must be running as a separate 
process and courier-imap connects to famd with the help of libfam.
