I followed your earlier thread (hopefully this is a related topic). This
is strange. By default, sendmail is disabled. You don't even have to put
anything into rc.conf:

# grep sendmail /etc/defaults/rc.conf

Sendmail listens and accepts local mail only. You can't connect to it
from another machine:

# telnet 25
telnet: connect to address Connection refused
telnet: Unable to connect to remote host

You must've tweaked something to make it behave differently.

Share with us your testing methodology. From previous thread, I
understand that you just want something to submit your local mail (from
daemons, scripts, etc). Then as others already said, a simple alias in
/etc/mail/aliases and executing newaliases is sufficient.
