Dear Roundcube Support Team,
I am experiencing an issue with one of our email accounts hosted on cPanel (Niagahoster).
Email account: *pajak.stp@tstjateng.co.id* pajak.stp@tstjateng.co.id
Problem description:
In Roundcube Webmail, the INBOX displays the message: *"No messages found"*.
However, in cPanel → Email Disk Usage, it shows that there are *49 messages in the INBOX*.
Email storage is not full (396.91 MB used out of 1 GB).
There are no active email filters.
The INBOX folder is subscribed (default and cannot be disabled).
This indicates that the messages physically exist on the server, but Roundcube is unable to display them.
Could this be related to:
IMAP index corruption?
Dovecot index/cache issue?
Roundcube cache problem?
Please advise on the recommended steps to resolve this issue.
Thank you for your assistance.
Best regards, Niko

I don't have CPanel, but the times I've had this problem, the user had the wrong permissions on their email folders.

It might be just that the messages are flagged as \Deleted. Take a look at options in Settings > Preferences > Server Settings.
You may want to check the messages to see if they are in an incompatible format like mbox.

mbox is not an incompatible format. Roundcube uses your MTA like dovecot to retrieve the mails, so as long as your mail server is configured properly it should be able to retrieve all your messages. I used mbox for years, inherited from an older sistem (openwebmail) which DID depend on mbox. We migrated to maildir because it is faster, more secure and easier to index and back up. (imagine having to delete messages from a 3GB mbox file)
