SMTP commands for "AUTH NTLM"

Question

I'm failing at finding the commands I need to send to authenticate to a SMTP server using NTLM.

I think it goes something like:

AUTH NTLM <bae64encode something>
334
<bae64encode something>
235

Answer 1

You need a Base64-encoded Type 1 message. Read this.

Answer 2

I've never been very good at reading RFCs, if you could give me an example I would be better able to read that RFC next time I need it.
