Squirrelmail “Invalid mailbox name” error with Plesk 9.2.1
A client today had a problem with Squirrelmail giving the following error, preventing the folder listing from coming up:
Query: CREATE "Sent" Reason Given: Invalid mailbox name.
To resolve the issue, I had to change some of the Squirrelmail folder settings in /etc/squirrelmail/config.php.
$default_folder_prefix = 'mail/'; $trash_folder = 'INBOX.Trash'; $sent_folder = 'INBOX.Sent'; $draft_folder = 'INBOX.Drafts';
This was on a RHEL 5.3 box, so the config.php may be located at another path if you’re using another distro.
