How to replace a user's missing mailbox

Introduction

A user's mailbox may become missing due to malicious activity, file system corruption, or accidental deletion. The user's mail folders can be recreated. However, lost messages must be restored from a backup.

Procedure

Please note that in the following procedure, $cpuser, $domain.tld, and $user must be replaced with the cPanel username, domain name, and email username, respectively.

1. Access the server's command line via SSH or "Terminal" in WHM.
2. Create the email user's mail folder.

   mkdir /home/$cpuser/mail/$domain.tld/$user

3. Set the folder ownership.

   chown $cpuser. /home/$cpuser/mail/$domain.tld/$user

4. Set the folder permissions.

   chmod 751 /home/$cpuser/mail/$domain.tld/$user

5. Run the mailperm script to recreate the mailbox folders.

   /usr/local/cpanel/scripts/mailperm $cpuser
