No, it means interpret as an IP address, it specifically says that (of course, it isn't directly talking about e-mail, but about any place where host names are used). As long as no top-level domains of 3, etc. are ever registered, this should not be a problem in actual practice. It uses that argument to show that the two cases are not ambiguous, you can always tell whether what is there is really intended to be an IP address or a host name. Remove "." from specials, and if you insist have a "SHOULD NOT" for leading or trailing "." in local-part. And ".." ? Personally I have no problem with this, but don't have anything that attempts to enforce any rules on local parts anyway. kre
