My example involved a machine which was NOT intended to originate
SMTP. Due to misconfiguration/bugs, it does.
that's what you get for running (probably) microsoft. don't expect us to
impair the rest of the network to accomodate their brain damage.
people need to be able to send mail from arbitrary locations on the
net.
Why? Are there NO solutions to the roaming problem, other than
allowing any IP on the net to originate SMTP to any other IP, and
claim to be from any domain?
there is no good reason to require them to do so.
this mail is originating from some earthlink.net IP address; the return
address is moore(_at_)cs(_dot_)utk(_dot_)edu(_dot_) it's perfectly valid
for me to be using
that return address to send mail from that IP, or from any other IP that
my laptop happens to be connected to.
Why? You're stating it like it's an axiom, or a law of nature.
it's the way mail is supposed to work. it's consciously chosen and highly
desirable behavior.
Is it really impossible for you to connect to a well-known SMTP
server, which can verify you, and verify itself as a well-known SMTP
server to others?
yes. furthermore, it would be undesirable to force people to connect to
servers that verified their identities.
