furthermore, these two choices are the same because:

both sendmail and postfix require you to enable them in /etc/rc.conf
and start them.

both sendmail and postfix require you to configure them to disable the
globally visible smtp service.  they will also both be happier if you
have done a bit more configuration of the system before you start

both sendmail and postfix will queue mail entered locally and leave it
there if the main process is not running.

however, these two choices are different because:

in order to use postfix, you have to specifically select it in the
/etc/mailer.conf file.

the mail that sendmail queues when the main process is not running
must be manually flushed, and/or you must also run a separate process
to periodically flush said queue (whereas postfix will clean out its
local inbound queue when you start it).
