As far as I know that's just not a valid email address and no email client
will accept it. I think that RFC822 defines what a valid email is and
name@IP-Address isn't one of the valid formats.

We have a deidcated server with a fixed IP (e.g =202.34.123.45)
and a running mail server but NO domain associated with it.

I tried to send several times from serveral mail accounts from all over
the world
emails to an eMail account on this server (e.g. to ).
Unfortunately this doens't work.

The SMTP mail delivery system seems to need a domain name and NOT an IP.
Why?

For web pages I can write http://202.34.123.45
Why is such a trick not possible for emails ?
