Corrupted index cache after migrating from maildir to mdbox

[Toni Mattila]

Hi,

You have broken maildir files with wrong S= in them. Usually produced by 
maildrop or courier imap's tools. You can fix them with 
http://www.dovecot.org/tools/maildir-size-fix.pl

If you compare ls -la and S= in the files you will see the difference.

Cheers,
Toni
