(Node.js) Delete IMAP Email

To delete an email, the "Deleted" flag must be set to 1 for each message to be deleted. You must also call Expunge or ExpungeAndClose to remove the emails marked as deleted.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS
