just shows how wrong you can be, doesnt it?
the fact that it is technically possible to run a mail server on a
dynamic ip address doesnt mean that it is practical to do so. even
aside from DULs making it difficult to send mail directly with any
reliability, it is actually impossible to reliably receive mail via smtp
direct to a dynamic IP - dynamic dns just doesnt cut it for MX records
(at minimum you're risking your mail bouncing or being intercepted in
the possibly small window of opportunity between when you log out and
the time when you login and update your ddns record).
similarly, you cant reliably run a web server or any other kind of
server on a dynamic IP address.
something that only works sometimes may be acceptable for a home user
that doesnt reaaly care that much, but they should just accept the fact
that they're only paying for a "best effort" level of service and quit
whinging about the fact that nobody cares any more than they do (and
probably considerably less).
