This is what I was looking for.  See inline comments:

                   ^^^^^^^^^^^^^^^^^^^^^^
Here it's trying to connect the the IPv6 address for mx1.freebsd.org but
is unable to.  I'm going to go out with a limb and guess that you're not
using IPv6 yet.  Apparently you can add the following to your cf file:
DAEMON_OPTIONS(`Family=inet, Name=MTA')
CLIENT_OPTIONS(`Family=inet, Name=MTA')

But I'm not a sendmail expert, so I can't verify that this information
is correct.

Why is this machine falling back to send mail via ns1?  If that's
intended, then ns1 needs to be configured to accept mail from this
system and act as a relay.

No, but apparently you need to tell sendmail that you haven't configured
IPv6.  Unless you're _trying_ to use IPv6, in which case there would
appear to be something wrong with you IPv6 config.
