Sorry, but it would be possible: > Domain Owners can specify which other selector to use on a per- > message basis by utilizing the BIMI-Selector Header You could set a different selector per email message sent. You could manage that with a wildcard dns entry and check the dns server logs. However, the draft is specified in such manner that the fetching would be done by the MTA, so the BIMI check and fetching wouldn't provide information to the senders. Only if a MUA tried to perform all checks itself (because its mail server doesn't support BIMI, for instance).
