Hello- I am using the Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5) setup, and just tried to change a virtual mail user's quota by editing the value of quota in the user's table. Unfortunately, that did not seem to work. The number in the db changed, but the quota reported by the mail server did not. I then descended to their maildir, and tried editing their maildirsize file, then restoring the group and owner but still nothing. In fact, the quota size became zero. Any ideas on why this is happening, or what I can do to change user's quotas after their initial account creation? Thanks, Howard P.S.- Amazon gift card for the first person to get this fixed.
