Wolfe,
Thank you for using SNDM.

I don't have a plan to implement SMTP AUTH, because:
- My mail server does not require authentication. So I don't have chance to test SMTP-AUTH.
- It is not so easy to implement "SMTP Authentication" defined by RFC2554, the full auth mechanism (AUTH-LOGIN, AUTH PLAIN, AUTH CRAM-MD5, etc).
- I'm very busy on my regular work and private things.
So it is a very good chance for you to contribute to the community!
