You seem to just make things up on the spot. There
are not "many" ways to send attachments in email.


Actually, there's a few that I can think of, none of which are
'standard' in the format sense, but, they all work...

There's a format. All attachments are base64 encoded.


I agree there's a format, but, you can use another 'encoder' for your
attachment. And you stick the encoded 'file' (which is a message now
as far as your email client knows) into the body of the email. And
send it. The receiver will have to take a few additional steps
themselves to decode it back to what it really is, but, no base64
took place and officially, no attachment was sent either. Just a long
message.

If it's an image it can be inline, in HTML, or sent as
an attachment. That's it.


Nope. See above. it can be encoded into the message body without
using base64. Treated literally as a message, not an encoded file
attachment, inline or otherwise. Even using straight hex character
conversion, AZ, etc.
