Is there an RFC that says what you should eat for breakfast? :) It is local issue, not under the realm of any RFC. The only RFCs that may vaguely apply are RFC821, 822, and 1122 in regards to the local part of e-mail addresses, since usernames make up the local part of e-mail addresses on Unix systems. In this case, RFC 821 and RFC 822 are quite flexible. With proper quoting you can even put spaces in the local part (ex. "my name"@domain.com). Basically the set of all possible Unix usernames is a subset of the set of all RFC821/822 local parts. The only other thing about "_" is hostnames. "_" are NOT allowed in hostnames. This is probably what you are thinking about. Tom
