Upon receiving sub requests, some list management software
attempts to sub the email address given in the From: header,
others attempts to sub the envelope sender.
Which behavior is correct, and why?
I took a quick look at RFCs 2821 and 2822 and did a bit of
googling but didn't find a good reference.
Does anyone know a good set of general guidelines for mailing
list software that makes reference to the relevant RFCs?
