The standard requires the rhs to uniquely identify the host. For dialup users, it might be convenient to use a rhs of the form johnsmith.dialup.provider.net even though this `host name' is not a valid name in the DNS. But the host master of the provider.net domain guarantees that a rhs of this form always uniquely identifies the dialup host of the user `johnsmith'. I hope you now understand the intent of the rhs of a message id. I've been so vague in saying `the standard' because I knew it's a pertinent RFC, but I forgot the number. Thankfully, Paul said it's RFC 1036. Okay, now you can replace `the standard' with `RFC 1036' in my previous posts... :-) kai -- Be indiscrete. Do it continuously.
