i was not talking about the port being broken per se. a perfectly
fine port used in place of a base system component can break a box
if additional configuration steps are not taken.

Sendmail: no emails from periodic(8), possibly other breakage
Bind: no harm at all as long as the resolver library is a separate
package

I'm saying that one should not be forced to hack the system by hand
after replacing a part of it with a port. As it is now, you cannot
e. g. install DJB's dnscache, put 127.0.0.1 in /etc/resolv.conf, and
expect the base Sendmail would start without complaining.

ok. :)
however, I understood the OP's problem as "how can I make FreeBSD
use Postfix to provide the mail delivery function", not "how do I
replace files that are part of the base Sendmail with Postfix".

nobody's flaming anybody, but ok.
