RFC 2822 is clear on what does not belong in the From field. From
Section 3.2.6:

  In all cases, the "From:" field SHOULD NOT contain any mailbox
  that does not belong to the author(s) of the message.

Furthermore, it has this to say about what goes in the Reply-To field:

  When the "Reply-To:" field is present, it indicates that the
  mailbox(es) to which THE AUTHOR [emphasis mine --RP] of the
  message suggests that replies be sent.

So no, it is not fine. Unless you want to assert that discuss at blu.org is
my mailbox or that the Mailman program at blu.org is the author of this
message then said program should not be writing or rewriting my From and
Reply-To fields.

Or you can ignore RFC 2822.
