Well, I have 1,4GB mbox test file with around 367 000 messages :) I also
tested 64bit file support with one >4GB mail file in Maildir. I don't
think the amount of messages or their sizes should affect Dovecot.
Except there's probably a few problems that could happen once UIDs are
close to their maximum value (4GB), have to fix those some day.

Huge mbox files aren't very good idea if you plan to delete old messages
or add new custom flags, they may result in pretty large copying of
data.
