Ralph is configuring a new email client on a workstation to use the Simple Mail Transfer Protocol $($SMTP$)$ and Post Office Protocol $($POP$3)$ email protocols. He wants both protocols to use encryption when communicating with the email server. Which port number should Ralph use to secure the SMTP connection with Transport Layer Security $($TLS$)$ and the POP$3$ connection with Secure Sockets Layer $($SSL$)$ encryption?
