I think I have it, at least it works now.

I added this block from 2.3 ...

service auth {
   client_limit = 1200
   unix_listener auth-client {
     group = postfix
     mode = 0660
     user = postfix
   }
   unix_listener auth-userdb {
     mode = 0777
   }
   user = root
}

I assume the 0777 etc aren't ideal.

Suggestions welcome.

But my basic setup seems to work now!

(thanks to all devs for their work, even when it's sometimes hard to 
keep up ...)
