Where UID is used now sounds like a good use case for UUIDs (or GUIDs?) that don't ever change.

- jcranmer 7y agoI don't specifically know the history of IMAP, particularly IMAP UID, but the semantics of UID to me implies that it was originally specified to permit its implementation as the file offsets into the mbox files that backed the store, and I believe some IMAP servers implemented it that way. Some IMAP server implementations have a custom attribute they use to indicate a globally-unique message ID.
