Sorry, missed to note that for your issue it is important to have
following 2 settings in your sendmail.mc as well:

FEATURE(`no_default_msa', `dnl')dnl
   -> this is default in the sendmail.mc shipped with CentOS

DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
   -> this is commented out with a leading dnl in default sendmail.mc
      the important part is the modifier "M=Ea": the "a" bit enforces the
requirement for AUTH on the MSA (port 587)
