Allowing IMAP/POP to Send EmailThe email SMTP protocol was created in simpler times. One of the problems is that it is far too easy for any one person to impersonate any other person on the planet. One of the things that will reduce spam and fraud on the Internet is to make it more difficult for one person to impersonate someone what they aren’t. But to do this we need to change that way email is distributed and do it in a way that is a natural evolution of the current system. In the beginning the Internet was a Unix network where every computer had its own SMTP server. One person would create an email that was submitted to the local SMTP server, the local server contacted the destination SMTP server and that server would deliver the message into the local email box. That method still works today but few people get their email that way. Sender --> SMTP --> Recipient Today we have more of a consumer model where consumers run email clients and leave the SMTP servers to their Internet Service Providers (ISPs) The user creates an email message that is sent to their local ISP who has an SMTP server. That server accepts the email and then transfers the email by SMTP to the server that stores the incoming email for that user. Then the recipient connects to their server by POP/IMAP protocols to download their email. Sender --> SMTP --> Sender’s ISP Server Sender’s ISP Server --> SMTP --> Recipient’s ISP Server Recipient’s ISP Server --> IMAP --> Recipient The problem is that anyone can impersonate any other person by setting their address to be anyone else on the planet. SMTP provides no checking to determine if the sender is the same person as they say they are. And the end user is using the same protocols to talk to servers that servers use to talk to each other so servers can’t tell if they are talking to legitimate servers or end users. I suggest a modification in the IMAP/POP protocols that allow for a two way transfer of email rather than requiring incoming email to be downloaded with IMAP/POP and outgoing to be SMTP. Sender --> IMAP --> Sender’s ISP Server Sender’s ISP Server --> SMTP --> Recipient’s ISP Server Recipient’s ISP Server --> IMAP --> Recipient If IMAP and POP were enhanced to allow outgoing email to be transferred back up the same connection as incoming email it would have several advantages.
