Popular MTA implementations (Sendmail, Postfix) do not implement the Sender: header the way 822 and 2822 suggest, so even before you consider mailing list managers you need to be very careful about RFC lawyering. Microsoft MUAs present message headers in a way that works best if normal messages do not have a Sender: field and mailing list messages do have one.
