RFC 4954 (<http://tools.ietf.org/html/rfc4954>) defines error code 535 as

<quote>
   535 5.7.8  Authentication credentials invalid

   This response to the AUTH command indicates that the authentication failed due to invalid or insufficient authentication credentials.
</quote>

IOW, either the user name or the password (or the combination of them) are not accepted by the server.

Here, a "AUTH PLAIN" (see <http://tools.ietf.org/html/rfc4616>) authentication did apparently fail...

... and the "AUTH LOGIN" failed, too.

*WARNING* - note that the login strings above contain your cleartext base64 encoded authentication tokens.  Thus, change them ASAP!!!!

Best, Albrecht.
