I have a mail infrastructure running on Cyrus (2.5.10), Postfix (2.7.1) and Perdition (1.19).
Recently many users have been complaining about their quota usage being displayed wrongly.
When trying to solve that using quota -f, the command returned a System I/O Error due to the nonexistence of some invalid mailboxes that are not even listed under ctl_mboxlist -d, such as: '' (empty string) and 'DELETED.user.teste3cyrus.5A902111EFJulho 2017.5B2E7DCF4DE7725F3314'.
Here is the full output of the command:
failed opening header for mailbox 'domain.com!DELETED.user.teste3cyrus.5A902111EFJulho 2017.5B2E7DCF4DE7725F3314': System I/O error: No such file or directory processing mbox list for '': System I/O error: No such file or directory
Can anyone that has ever faced something like this help me out?
PS.: I tried to find a way to fix the quota of a single mailbox, with no success. The docs of the quota command only state that a mailbox prefix can be used, but no pattern on that is shown. I've tried firstname.lastname@example.org, email@example.com, mailbox-name, but none of those worked.
