Maybe I misunderstood.

I thought that BIMI said: If a message is delivered by the system and meets 
some other conditions, then it gets a reserved flag, which the user is 
unable to set (or clear). And my response to that is that people expect to 
be able to copy their mail from one server to another. When messages are 
migrated then they lose the magic BIMI flag, because the new server sees 
them being inserted by the user using IMAP APPEND.

This sounds to me as if it rather diminishes the point of BIMI...

That some servers don't support flags is okay. The servers that can't be 
extended don't get a lot of new extensions anyway.

(BTW, John, you reject my mail as spam. Even though I've been practically a 
hermit for a year now. I made this list-only on a whim.)
