This looks correct, but for the last line I have instead match for any from any 
auth action send.

Not sure if that makes a difference though. My understanding is that if you 
don't specify from where, it's local by default, and authenticated messages are 
supposed to be treated as local.

I think the message is pretty clear: your server doesn't ask for a password, 
but msmtp tries to send one.  You'll have to uncomment the auth table and the 
auth argument on the listen on directives.

Maybe you could try and use openssl to test and see what the server answers 
exactly.
