IMAP requires a password. SMTP it's optional. I think that consumer SMTP should be replaced with not only something that requires a password, but that the user has to log into the account that they are sending email from. SMTP doesn't have to be tied to IMAP accounts. If you have an SMTP account you can spoof anyone. My idea with IMAP sending is to deny the ability of the sender to use a different email address that the one that they are logged into. This is to prevent spam and spoofing.
You are talking about implementation details, not protocols here. Assuming you could send over IMAP, why do you think it would any more likely that spoofing would be blocked by all implementations than with authenticated smtp or that all accounts that accepted IMAP logins would be valid sending addresses?
