Well, Eudora certainly is. The specification of PLAIN authentication
(RFC 2595) states that the auth data is sent on the same line as AUTH
PLAIN.

The LOGIN method expects its data on two subsequent inputs. Has Eudora
got confused between PLAIN and LOGIN?

There is, AFAIK, no published authentication mechanism that has just one
subsequent data line of plain text. However, Exim is highly flexible in
this regard. You can configure its plaintext authenticator to operate
like that if you want, by setting a suitable value in server_prompts.
