void smtp_debug (SMTPSTREAM *stream);
void smtp_nodebug (SMTPSTREAM *stream);
which are mentioned in the docs and are prototyped in smtp.h are not declared in smtp.c or anywhere else as far as I can see. (using imap-2004a)
You are correct; this was never implemented as it was decided not to do debugging this way.
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.
