Well, looking here:
http://www.fehcom.de/qmail/smtpauth.html
In the line with AUTH CRAM-MD5 is no need for more data.
The answer from the server seems to be valid.
After dumping the network traffic between client and server
I can see a base64 encoded string with user and another encrypted
string sent by the client but not displayed in the sendmail log.
In the log immedeatly appears a "STARTTLS=read, info: fds=6/4, err=2"
followed by "--- 535 5.7.0 authentication failed".
The login data sent by the client seems to be right, at least
the username is correct. Is it possible to decode the part of the
password with command line utilities?
Are there any other hints?
