That's a lot of emails! :-)

I had a quick look at poplib.py and I couldn't see any limit in the
code itself. Perhaps it's the gmail server that's doing it. Can you
retrieve the later messages, eg have you tried M.retr(500)? If you can
then you could just try retrieving messages beyond what M.list() says
until it says there's no such message.
