The Undo Sent E-Mail (USE) Protocol

This paper provides the sender of email the power to undo his sent mail. I provide my own idea in implementing this undo function in sending mails with my own protocol called the USEUndo Sent E-mail. This is achieved by adding an extra functionality to the domain's SMTP server and the message can be pulled by both the sender and receiver from the POP3/IMAP server. IMAP (Internet Message Access Protocol) -is a standard protocol for accessing email from your local server. The POP (Post Office Protocol 3) protocol provides a simple, standardized way for users to access mailboxes and download messages to their computers. The HTTP protocol is not a protocol dedicated for email communications, but it can be used for accessing your mailbox. If the sender pulls the mail first, then it means he has successfully retrieved the mail and if the receiver pulls the mail first, then it means the receiver has read the mail and the mail cannot be retrieved. We achieve this by implementing the USE protocol.
