electrons move pdq, and i don't think it was ever designed to be
"non-instant". if you have the time or inclination to provide any original
sources on the intentions of the designers, it'd be interesting to see if
they go out of their way to say in the original spec "oh, by our design, it
might take hours for you to get your email, so don't count on it being

in that same vein, i don't think the original designers of email thought
"hey, let's not make this reliable."
by common usage of the term reliable, email *is* reliable, and it many cases
it's more reliable than the phone service or postal mail. however, by
strict definition, it is not - but then again, what form of communication is
reliable by the strict definition?
to tell users "sorry, my email server is configured to aggressively kill
'spam' and have multi-hour delays on suspected spam, and i can't help it if
you didn't realize that email was designed to never really be an instant,
reliable form of communication, tough beans" is kind of bogus and lame imho.
i'm not an email-original-designer-intention-historian, so please correct me
if i'm mistaken.
