Hmm.  Just looked at it.  Multiple "From:" appears to be legal, since
it's not explicitly prohibited (and text at the beginning says that
multiples are allowed unless explicitly prohibited).
 
Not only that, RFC 822 itself contains examples of "From:" fields
containing multiple addresses, so *that* is certainly legal.  My
presumption is that:
        From: a
        From: b
should be treated the same as:
        From: a,b
but I'm not certain.  The latter is clearly legal *by example* (although
there's a requirement here that "a" and "b" be replyable addresses).
 
Cheers,
