I figured this out.  I was testing Dovecot from the machine running 
Dovecot.  I didn't know that when the client address is a local address 
(even if it's a public one), that Dovecot treats the connection as if it 
was localhost.  I also did not know that Dovecot automatically ignores 
ssl = required and disable_plaintext_auth = yes for localhost 
connections.  As this renders pretty much my entire email moot, we can 
call this one solved. :)

Please reply on list.
