    If you’re using IMAP to fetch the mail from the remote server, the mail will be ordered by ascending IMAP UID. By default, the higher the number, the more recently it was added to the folder:

    Unique identifiers
are assigned in a strictly ascending fashion in the [folder]; as each
message is added to the [folder] it is assigned a higher UID than the
message(s) which were added previously.

    However, that doesn’t mean that messages are downloaded in ascending date order via IMAP. If you move a message from one folder to another, it gets a new UID and is moved to last place in the new folder. And if the IMAP UID Validity Value is reset, all bets are off — the messages could be renumbered in any order whatsoever.
