Can I somehow disable the CRAM-MD5 authentication for a SMTP-Stream using c-client (like pine does) ?
It's the DISABLE_AUTHENTICATOR function of mail_parameters(), e.g. mail_parameters (NIL,DISABLE_AUTHENTICATOR,(void *) "CRAM-MD5");
Note that this is a global setting. You should only use this as a workaround, and instead convince the manager of the SMTP server to fix their server.
Thanks, works nicely. Still will try to get the people to fix the SMTP server...
