One of the benefits of the suggestion to use the regular posting

However, it assumes that the path for outgoing mail is related to the
path for incoming mail.

Well, before I sent my first post on this, I considered that question, and I could argue it either way. If the requirement is a trusted channel from MUA to the reporting mailbox, then yeah, an asymmetry is a problem. Otherwise, it's ok.


If the two paths are not related, then sending something to the
outgoing mail path won't have any effect on incoming mail handling.

Not quite. The outgoing mail path is a posting agent, not a delivery agent. The /address/ specifies the delivery agent. That's why this is an issue of trust, not routing. Since the domain name or possibly full email address of the reporting destination is taken from the pickup host, there's no question that it points to the right place. Hence, any valid posting server ought to be able to get the report there. The problem is whether the reporting server /believes/ that the report is valid.

If there is a configuration asymmetry, then the report will come from outside the trust boundary.


Also, everyone's talking about POP and IMAP as if they were all there
is.  What about cases where the user's mailbox is accessed other ways?

I think the latest round of discussion has eliminated any interest in the message retrieval mechanism.
