From my point of view; outgoing MTA can be any server in the world.
How could I know I should temporarily add record for MTA of some
ISP the hotel is using ?
Please read the LMAP discussion paper. It addresses this issue.
Nice. I'll quote: LMAP discussion paper, page 1.
'The LMAP protocol falls with the scope of "changes to existing
applications"'
In ideal world, we would throw away SMTP [and bunch of other protocols,
too].
In real world changing all MUAs, MTAs, firewalls, proxies - all software and
hardware built around this crappy protocol - is way too big overhead that it
could happen now. We have the spam problem now.
Anyhow, this shows interesting problem for someone to think about.
How to make Internet capable of changing or upgrading protocols
every now and then?
I'll turn your question on it's head: why is it the problem of the
recipient to do the work to tell your travelling salesmen from
spammers who are abusing your name?
My answer is that it's not. I'll just toss all of the forged
messages into the garbage, and your travelling salesmen will never get
my business. That's fine by me, as I'd rather work with people who
don't abuse the network.
As Hadmut said in his rants in the RMX paper: People have to realize
that if they want to stop forgery (for spam), they must stop their own
forgery.
Good point. I agree that forgery is a big problem - but what can
we do about it as long as we have current infrastructure?
Anyway, LMAP seems to suggest major changes to MTA
which will lead to major resistance in adopting organizations. It'll happen,
but it's just a question of when. Quick acceptance of HTTP shows that
big moves can happen quickly, but there has to be benefit with it, too.
[Yeah, getting rid of the spam could be it, but isn't - new system should
have something "new" you can't possibly get using "old" stuff]
We [people] are very good to adopt new things, it's just that we're
very lousy to give up the old things.
