> Is there a way of sending "ordinary" E-Mail to an X-400 address? Yes, but it takes some effort and it depends on your mail client. And if the X400 system is linked to the Internet via a gateway. Try putting the whole of the X400 address in the "To" field - something like this:- /S=Glowinski/G=Andrzej/O=ORGANISATION@MAILSERVER with the appropriate items substiuted. Better still, get someone who knows what they are doing to send you a message from the X400 system, and try replying.
