How To Secure Emails Smartly

Email is inherently not secure since SMTP does not encrypt messages. Messages sent through SMTP contain information about the computer that it sent from, and the email program that was used. The POP and IMAP protocols do not encrypt the username and password you used to login. The email messages you send may be saved unexpectedly and indefinitely and may be read by unknown persons as a result.
