I'm sure this question has been asked before, but I'm just
as sure I haven't seen it!

What is the standard for e-mail interchange in UNIX, and what
if any are the documented references?

Specifically I have a problem with From lines. I had always
believed that if a line started with From, it was the start
of the next message, otherwise it would have been pre-empted
by a >. However we have started receiving mail from an Ultrix
machine which has the bad manners to use From twice in a 
message. The UNIX (mailx/mail) software understands, and ignores
the extra From. How does it tell???????

Please e-mail replies, and I'll summarise etc etc.

Thank you,
	Matthew
