What Are These cur, new, and temp Folders in My Mail Directory?

Currently, cPanel only supports Maildir, a directory that stores email messages as files. Maildir works with Courier, a mail server that provides folders and quotas for the email accounts on your hosting account.

The folders inside the mail directory are subdirectories such as .Drafts .Trash and .Sent. Each of these folders contain three additional subdirectories called tmp, new and cur.

  • tmp - This subdirectory stores email messages that are in the process of being delivered. It may also store other kinds of temporary files.
  • new - This subdirectory stores messages that have been delivered but have not yet been seen by any mail application, such as webmail or Outlook.
  • cur - This subdirectory stores messages that have already been viewed by mail applications, like webmail or Outlook.
