We need to think about what the endpoints are in the email scenario...

Well - even if email doesn't guarantee delivery, the general public's
expectation is that it does. It's not just program committees :-) it's
a fact of the world which I have personally encountered on several
occasions, just like (I assume) many of us: people believe email to
So, in order to give people the desired (even expected!) service, we
should make it reliable.
The end points, however, should be my outgoing SMTP server and
your incoming POP or IMAP server. This is the communication
that we assume to be trustworthy and reliable - not the communication
between your email client and mine. If my personal email client's spam
filter deletes emails, it's my fault and I would be inclined to accept it.
If I didn't configure that filter, I'd assume that it's the client
fault, and complain to them (or someone else would).
It's the same thing with the post office - people assume the
communication path from my post office to yours to be reliable,
or at least *quite* reliable. If the US post office would start
losing 50% of your letters (I know, email isn't doing that, but
it's getting worse, and we ought to pull the break before it's too
late), people would get heavily annoyed, and misunderstandings
Hmm, didn't the UK just give us an example of that? :-)
