Well, with v1.1+ it's possible to preserve both POP3 and IMAP UIDs (each
line is <IMAP uid> P<POP3 UIDL> :<filename>). I guess the script doesn't

The added mails are ordered by their filename. The filename typically
begins with timestamp of when the message was received, so it's
practically in the same order as mails were received.
