[Dovecot] Fixing bad maildir message sizes

[Richard Platel]

Hello.

As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename.  These messages cause dovecot 2.x problems.

I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename.  However, when I do this, dovecot gives the message a new UID on next login.  If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login.  If I change dovecot-uidlist and delete the index, then the UID is preserved.

Re-indexing our millions of mailboxes is not a great solution for us.  Is there a good way to fix this?
