Sounds reasonable.

Right.

This may be too soon.  mlfi_connect gets called when the socket is
opened.  The client doesn't send AUTH until after EHLO, so I think the
soonest that {auth_type} can be set would be in smfi_envfrom.  Which
actually makes sense, because you mentioned above that auth_type is in
Milter.macros.envfrom :)
