search all folders by message-id?

[hamann.w at t-online.de]

I am looking for a way to locate a message in any folder.
Of course I could examine all folders in turn for a given message id,
but the way cyrus does duplicate elimination across folders suggests that
there might be a more efficient way.
Intended purpose: record message-id of certain mails outside of the mail store
and retrieve them even if they have been moved to the wrong folder
