I am a student worker in Enterprise Systems at the university I attend. We are in the process of converting to a new version of Exchange. We are attempting to use telnet to track messages in our test environment but we can not figure how to correctly input AUTH NTLM username/password string. It needs to be converted to base64.

  • What would the format be?
  • Something like "domain/user password"?
  • Sorry if this is not worded correctly, as I am still very new to this. If this is totally wrong, what would be the proper steps to connect on port 587 with ntlm?

Not so simple: NTLM does not transmit passwords in an unencrypted form. Here is an example SMTP session with NTLM authentication.

Actually, this document describes in detail the work NTLM - I recommend to read for understanding.
