mail on the other hand (the paper variety) will meet the inside of my
paper bin without delay if I receive it through the mail, but if my
boss gives it to me and asks me to look at it, I look at it.
With many of the current protocols, SMTP being a prime example, there
are very many ways to do things that weren't foreseen, or at least not
specifically accommodated, in the original protocol. That was great
because it allowed innovation. Unfortunately, the most innovative
people around these days are the spammers and fishers, so these days,
when we come up with new protocols, we need to specifically allow
everything that's good so implementations/users can reject everything
else. I.e., a new mail protocol will have to address things like
forwarding and mailinglists explicitly.
I couldn't make sense of anything but the last sentence, but I agree
with the last sentence.
