Interesting, thanks for the link. Not inserting the header when not
necessary is the right thing to do anyway, but I am not even sure yet it
will solve your problems. 

THe header adding was done whenever a message is "saved" on an IMAP
server, and apparently this is what we do in the IMAP<->IMAP case. I am
not sure why that would be needed on the local IMAP message anyway, so
this would need investigating.

I have not looked at how the UID translation stuff works, as I don't use
it myself.

I bet it does confuse it :-).

Right. So don't let us insert it when not needed. The patch to do it
properly is not that difficult.
