In my headers, you will see a field called "Sender". I didn't add this field.
I don't really object to it... but the Lsoft "listserv" mailing list package
does. Whenever there's both a From: line *and* a "Sender:" line, listserv
concludes that the Sender: line is authoritative. Unfortunately, it's wrong;
my "From" address is my "real" email address, the "Sender" address (obviously)
changes whenever I move from one machine to another.
Where did "Sender" come from? Is there an RFC discussing what it's for?
I notice that in NMH, this is suppressible with "draft_from" masquerading.
So, I assume it's now considered optional. Any history on this?
