If getting rid of the "random SMTP sender" problem means that
the
roaming user is required to use a home server, then that's fine.
It stops the spammer, and has little cost to the roaming user.
no, it doesn't stop the spammer. it just makes life harder for
legitimate users.
Could you elaborate this? I don't see how this should make
life harder. In my experience, it makes legitimate users's life much
easier and cheaper.
there are legitimate needs to be able to send SMTP from random
places on the Internet, even from dialup lines. preventing users from
doing so makes it easier for the ISP to trace complaints, but it really
doesn't prevent people from spamming. it just means they have to use
throwaway accounts.
you're not authenticating him in any event. source IP addresses are
not authentication. and domains have nothing to do with IP
addresses.
Currently domain have nothing to do with IP addresses.
Currently we have a severe spam problem.
Maybe it's not so wise to insist on keeping the current status quo.
that's like Mr. Bush's logic:
no matter what the source of the problem is, bomb Iraq.
maybe it's not wise to impose barriers that block legitimate use,
decrease network transparency, and don't actually solve any problem.
only because you haven't thought it through. many spammers use
throwaway accounts anyway. the fact that they are using their ISP's
SMTP server to relay spam doesn't keep them from spamming.
Again, could you elaborate?
If they had to use their ISP's SMTP server, this server will stop them
using wrong domains. That's the first step to stop spam.
there's no such thing as a wrong domain. people need to be able to
originate mail from other domains than the ISP's. and it won't stop
spam, because the spammers will just use throwaway accounts.
