I just wish, people would work on open email features and fix things...

email can still be fixed, at least for semi-open systems. but noooo instead we build a myriad of other things.

Things to be fixed/extended:

* MIME * Support for SMIME/OpenPG Encryption with IMAP (like, when emails come into a imap inbox they are encrypted with a certain public key and signed with another, or when a email has to be saved, there's a standard, that emails can be saved encrypted in the inbox) * quite a few sieve extensions for more filtering/action possibilities * Publishing of Mailservers from whom they will/won't accept emails (or attachments) * better support of markdownn (markup/mime) type in emailreaders, there's even an rfc for it!
