A customer of ours, who uses Mail from Mac, after last cPanel/WHM upgrade cannot send messages or even delete the message. How can I solve, please?
The error says ...

In Mail's Preferences, go to Accounts, select the email account, switch to the Server Settings tab and click the Advanced IMAP Settings button. There the IMAP Path Prefix can be set to INBOX.
