I've tried copying a big offline Thunderbird mailbox to a live Dovecot 
server, and it worked for the first 11,880 messages, but now won't do 
any more. I know Dovecot can handle more because this came from an 
earlier instance of Dovecot.

Just one of the reasons why I think I need to replace Dovecot, but for 
the little detail of not knowing of any IMAP servers that are 
necessarily better.
