Not if it still happens with -1, which should cause OfflineIMAP to run
in single-threaded mode.

UW-IMAPd is known to do weird things like this, unfortunately.  I'd say
about 2/3 of the problems people have with OfflineIMAP are with UW-IMAPd
servers.

I have always run Courier with good luck, though I don't believe it
supports mbox.  I think pretty much any imap server will work better
than uw-imapd.  I've heard of a few problems with bincimap, but other
than that, most work just fine with OfflineIMAP right out of the box.

This may or may not be possible, depending on your specific IMAP server.
OfflineIMAP certainly takes every effort to avoid changing flags on
messages during a download, but some IMAP servers will treat any
download as a read.  In any case, once a message is read on a local
client, that does change a flag that OfflineIMAP will propogate back,
and it should result in the "N" and "O" being removed.  Alternatively,
if you use IMAP or OfflineIMAP clients for all your mailbox accesses,
you should have no trouble (IMAP does not differentiate between N and
O).
