Well, since no one else has come along yet I'll give you what little I
know from my meager experience:
You have to have From. Not the From that prints for the recipient, but
the From header in the envelope.
I think the Return Path is derived from that.
You need to identify the content type. e.g. texp/plain, etc.
Then the doctype, and etc. etc.. PHPNet and W3 schools both have good
articles on them; I'd do some checking there to get going if this is new
to you. Basically you have a set of requireds and then a set of "if you
wanna" types of headers.
I'm new at this too so getting too specific would be the blind leading
the blind <g>.
