Alas, it hasn't solved the problem - still getting duplicate messages in thunderbird.  So far it appears that mulberry is a little happier, but I find some messages are missing - such as the archive of the dovecot mailing list jumping from 2015-03-21 to 2015-04-14.  

I tried # rm -r dovecot.id*

Would "maildir_broken_filename_sizes = yes" have any impact?  If it does, then I'd think your fix sizes script would be worth a try.

If all that fails - is there any reason to think that sdbox will be better behaved?
