My problem with it is the same problem I've always had: the
responsibility should be on the client smtp, not the server. How can
the client smtp know the server will encode the VERP correctly?
And, why should the server smtp dictate the form of VERPification?
What if the client smtp wants an arbitrary and unique cookie?
It would be better to send as many "return paths" as recipient
addresses, but only one message. This might end up looking like:
