Thanks.  I tried that and some other things (eg service.switch).  Even
read the book and help files some more.  Terry's suggestion regarding
"expensive" seemed like the opposite of what I needed (I was trying to
keep the msg out of the queues) and I had no luck trying to disable some
DNS which he hinted at.

I got my first good clue after adding level 15 logging to see an 80-sec
delay between MUA-launched sendmail and the MTA daemon.  I then used
level-99 logging to find

Jan  3 13:43:56 localhost sendmail[63611]: h03Lgf6p063607:\
    makeconnection (localhost.localdomain. [IPv6:::1]) \
    failed: Operation timed out with localhost.localdomain.

I shoulda considered that one big config difference between my 4.7
config and 5.0 is custom kernel without IPv6 on 4.7 and still using
GENERIC kernel with IPv6 on 5.0!  I do have
    ::1			localhost localhost.localdomain
in my /etc/hosts, but there's apparently something else wrong.

Is there a quick way to disable IPv6?  While I figure that out or
rebuild my kernel, I got a quick fix by changing, in my "submit.mc",
this
    FEATURE(`msp')
to this
    FEATURE(`msp',`[127.0.0.1]')
