How to Fix Mailbox Permissions using the command line

Introduction

Occasionally, your users' mailbox permissions may be incorrect after a migration from another server. This can cause issues with sending and/or receiving email. cPanel includes the mailperm script that can be used to correct permissions on mail files within an account.

Procedure

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the mailperm script for the user.

   /usr/local/cpanel/scripts/mailperm --verbose $user
