You need to make sure that your smtp server does NOT require
authentication. If so there is NO need for user, password and encryption
and you should get NO authentication error.

If your smtp server DOES require user and password, leaving user and
password out will lead to an authentication failure (as it requires
authentication at server side)

Fact that you get the errors means gb.net.smtp does communicate with
smtp server, as these errors codes are generated by smtp server (giving
you the reason what goes wrong).

I cut this piece out of an earlier post you wrote:

See the line 250-AUTH LOGIN PLAIN and 250-AUTH=LOGIN PLAIN.
Seems like even when using SSL user and password is passed as plain text
and thus refused by smtp server leading to an authentication failure.
So seems documentation is correct on plain text password being passed.

Leaving user, password and encryption out will only work if smtp server
allows access without authentication (as explained above).

Have you been having private mails as I wonder about the routine or are
you mixing up names (Rolf <-> Willy) and mean the routine I posted?
Because if so, feel free to use.
