Hi, Could anyone explain me or direct me to information how the maildirsize file is calculated. As I understand this is updated every 4 hours. The issue I'm facing is that from time to time the sync with the size reported and the actual usage of disk space on the server is inconsistent. I have to contact my provider each time to have it corrected. They reply to me that I'm the only one having these issues out thousand of mail users. But the issue stays unresolved. The issue is with a mail client Evolution 2.32.2 running in a Linux environment against cPanel 11.28.87.
