Failed to lookup mailbox status: Mailbox doesn't exist

Symptoms

Opening the Email Disk Usage menu results in an error such as this:

CONFIG_TEXT: [INFO]=[Mailboxes::get_mailbox_status_list(HASH(0x37eee78)) failed: “/usr/bin/doveadm” reported error code “68” when it ended: doveadm(username): Error: cmd mailbox status: Mailbox INBOX.user@domain_tld: Failed to lookup mailbox status: Mailbox doesn't exist: INBOX.user@domain_tld

Cause

The email account has been removed, but the (now broken) maildir symlink is still in place.

Resolution

Note: Make sure to replace .user@domain_tld with your actual email account and $user with your cPanel user.

1. Log in to SSH or the WHM Terminal.

2. Check for broken symlinks in the user's home directory:

   # find /home/$user/mail -xtype l

3. Unlink the broken symlinks:

   # unlink /home/$user/mail/.user@domain_tld
