Thanks a alot for the immediate response.
I have implemented the logic for SMTP Authentication as per the RFC for
CRAM-MD5 method of authentication.
And I also find that the output of my program matches the example mentioned in
But when i try to authenticate with my local servers , it fails.
I will mention the inputs I gave for encoding and the output .. Pls do let me
know if something is wrong.
Base 64 encoded challenge string : PDE3MDA1NzUwLjM0NkB0ZXN0c2VydmVyLmNvbT4=
Username : user1
Password : user1
CRAM-MD5 output string : dXNlcjEgNTMwYTdmNTJlNWU2MTE5NDRkNzliZjM5YjBmNmU0NDA=
But I get Authentication Failed for this input from the SMTP Server.
Pls help me.

Read the RFCs!
It's all there in RFC 2195. If it's urgent, I'd have thought you'd have
looked there already.
Also, there's a freeware CRAM MD5 checker program out there - Google for it,
that'll probably help.
