How can I quick delete all emails for saving disk usage?

I need a quick way to bulk empty all emails for one domain (include all mailbox users as well). How can I do that?

I checked CrossBox but they didn’t have the clean button. I deleter manually emails received.

I missed some thing?

Look like I found PURGE folder in Email Manager Tab that can delete all mails in inbox, spam, IMAP folder.:kissing_smiling_eyes:
