I think the way we ended up with headers of the form "@ node" <user> is that it got '@node:userid' as the address. Probably, some site used [log in to unmask]:IBM-Nets%bitnic.bitnet' as the address. I am told that this *IS* legal syntax, but I can't remember whether it is RFC822 or RFC733 that allows this flake. I know that *I* sure don't like it. Ah, for a fully RFC822, full-domain world.
