Empty mailbox

Übersicht

Whenever a user exceeds his or her storage, an e-mail client may report zero e-mails present despite there actually being mail in the mailbox.

Ursache

The mail server, Dovecot, uses a few cache files to speed up mailbox access on your account. In certain circumstances, these caches can become corrupted due to lack of storage. Consequently, whenever the cache is accessed by Dovecot, it returns incomplete information about your mailbox that is rendered as an empty mailbox.

Lösung

1. Login to the Bedienfeld
2. Ensure the user has sufficient storage available via Benutzer >  Manage Users
   • If not, edit the storage limit for the user via the Edit action under Actions
3. Under Dateien > Datei-Manager, navigate to the user’s home directory
   • This directory will be named as /home/<user> wobei <user> is the user whose mailbox is corrupted
4. Navigate to the Mail/ folder
5. Delete files dovecot.index, dovecot.index.log, und dovecot.index.cache
6. Access e-mail again. Problem is resolved.
