This means your ISPs server does not support that authentication method.
You should try the plain text login authenticator changes that I
suggested in my original response. It's not insecure as you set it so
tls is required.

If you telnet to their server on port 25 and issue a EHLO it will tell
you the supported mechanisms. You'll see something along the lines of:

250-AUTH PLAIN LOGIN

This service supports PLAIN and LOGIN methods, but not CRAM-MD5.
