It looks like it probably isn't, but it could be. A host could even have just "z." as its FQDN, given the appropriate DNS records. > So the requirement for the rhs to be the system name would > contradict this example. I think user-login-name@system-name would work best for news, but nothing specific is required. I think user-mail-address would work too, though not as well, based on the explanatory text in 2.2.2.

I don't think I've ever seen them, so my information may be well out of date. paul
