I believe the default settings in rc.conf for sendmail has gone
through some changes in 5.x.   The default behavior in 4.x was to
allow inbound connections for sendmail, which has changed to local
connections only in 5.x

Adding the follow to rc.conf should fix the problem...

     sendmail_enable="YES"    # Run the sendmail inbound daemon (YES/NO).
