Hi Listers, I'm using SMTP_UTIL to send emails from inside an Oracle database. It's a 10gR2 running on HP Unix. Currently I'm using "AUTH LOGIN" authentication method. For some reason I need to change the authentication method to "NTLM". I read about NTLM and the way it works. Apparently the server expects 3 encoded responses from the client. But I'm not sure how to implement it in an Oracle Stored Procedure. Does anyone have a sample that I can use? Appreciate it. Regards, ~ Amir Gheibi
