@NGIZero >Email is a minuscule text file that you transmit across the internet. I wish, but it's kind of a session based TCP protocol with no "file" to speak of - only addresses, a header and body.
With a protocol reference, sending an email with netcat manually is trivial, unfortunately most mail servers will refuse to accept email sent via that method.
Due to MIME and the huge amount of inflation base64 results in, any emails with attached files are hardly minuscule.
Indeed email should just be files transmitted encrypted over the internet anonymously via rsync or a similar file transfer protocol, but we can't have that can we?
@not_benis Please explain why you shouldn't be able to send emails anonymously?
After all, the email could contain private personal information that you only want the receiver to be aware of and the only way to reliably achieve that is for it to be encrypted and sent anonymously without revealing metadata.
