[Dovecot] Mail quota usage errors

Hi:

We're using dovecot with qmail and vpopmail and are having problems with major inaccuracies in the mail quota usage maintained in the maildirsize file. Although the file starts off accurate after we delete it and force a rebuild it quickly becomes inaccurate. It doesn't seem to be catching new mail added to the directories. Does anyone have any suggestions or links to pages that will help us troubleshoot/correct this problem.

Best Regards,

Jeff Koch
