While those numbers being in sequence sounds relatively normal, the number on how high they are isn't. Our issues would stem with e-mails starting at X-UID to 1, and then be fine for say, ten e-mails, then suddenly afterward, we'd see an X-UID header with a very large number, throwing our UIDVALIDITY off, causing a BOGUS sequence error. The postfix changes we made solved this issue for us. This happened mainly in IMAP connections, but POP connections were having the multi-download errors you were mentioning. We're using the older format for the mailbox format, so for now, they're simple flat-files, and we have to use both POP/IMAP, generally POP for POP connections for clients, and IMAP for Webmail clients. It's really a crap shoot until you have something sanitizing the incoming mail at the MTA point or at delivery to local mailboxes. Hopefully the Postfix changes will help you out.
