Yeah, it's not pretty.  But I'm not sure we're gonna have much choice
if Gmail changes their policy.

IMO the footer is a *very* good idea; when we started using the current
form of that, it greatly reduced the amount of "how do I unsubscribe"
noise.  But having said that, it probably wouldn't need to be on every
message to be effective.  I personally like the subject-munging but
could live without it.

[ thinks for a bit... ]  I wonder whether we could do something like this:

* Leave the From: and Reply-To: alone.

* Add the footer only if the message isn't DKIM-signed.

* Give up Subject-munging.  (Munging only non-signed messages would be
way too confusing.)

I think that would put us in a situation where DKIM signatures would still
pass, at least unless the source insisted on signing Sender: too.  We
might still have some issues with SPF checks, but not breaking DKIM would
be a step forward.

If things change to the point where only a small minority of messages get
the footers because most people are using DKIM, then we might have to
reconsider that part.  But that seems far away yet.

                        regards, tom lane
