Take a look at /etc/defaults/rc.conf for all of the gory details.
You probably meant sendmail_enable=YES, but:
# Settings for /etc/rc.sendmail and /etc/rc.d/sendmail:
sendmail_enable="NO" # Run the sendmail inbound daemon (YES/NO).
sendmail_pidfile="/var/run/sendmail.pid" # sendmail pid file
sendmail_procname="/usr/sbin/sendmail" # sendmail process name
sendmail_flags="-L sm-mta -bd -q30m" # Flags to sendmail (as a server)
sendmail_submit_enable="YES" # Start a localhost-only MTA for mail
submission
sendmail_submit_flags="-L sm-mta -bd -q30m -
ODaemonPortOptions=Addr=localhost"
# Flags for localhost-only MTA
sendmail_outbound_enable="YES" # Dequeue stuck mail (YES/NO).
sendmail_outbound_flags="-L sm-queue -q30m" # Flags to sendmail
(outbound only)
sendmail_msp_queue_enable="YES" # Dequeue stuck clientmqueue mail
(YES/NO).
sendmail_msp_queue_flags="-L sm-msp-queue -Ac -q30m"
# Flags for sendmail_msp_queue daemon.

Yes, but using a local domain which conflicts with existing domains
is strongly not recommended. Consider what happens if a local config
issue bounces email or worse to somebody else, or consider what
happens if you chose ".net" or ".com" instead of ".localhost".

The zeroconf/rendezvous stuff likes to use ".local" as the domain
unless other info is available.

Yes, absolutely, or to bounce email back to the example domain.
Network admins get cross when you pretend to be in a domain that you
have no affiliation with and they have to get your ISP to clean up
after you.... :-)
