I would like to point out that, at least in the case of Gmail, the UIDs of emails are changed if they are moved from one folder to another. Even if moved back to the same folder the UIDs get incremented and thus changed. I found this the hard way after relaying on the notion that UIDs do not change as I found almost everywhere in the docs.

Please note that message_id in the header is NOT the UID - and its dangerous to use as many mail progs don't put a message id in

Be aware that the uid is unique in a single mailbox. That means a message can have as much uids as mailboxes

The uid will change in case of unsing imap_expunge. Be shure that all work ist done before using imap_expunge.
