For me it doesn't really matter. I have two servers, and both are
accessible only from private networks. But if I found something I
believe is odd, I usually report it.
Returning "user not found" may be more useful for troubleshooting.
("Is the password wrong, or is @domain needed after username??")
Public accessible sites probably like a generic "authentication failure".
On the other hand, according to RFC 3501 in section 11.2 page 93:
"A server error message for a failing LOGIN command SHOULD NOT specify
that the user name, as opposed to the password, is invalid."
(Why not the same requirement for AUTHENTICATE ?)
