If so, it seems to have been backed out by the time it was frozen. My
copy of 2821 says (excerpted, of course):
Domain = (sub-domain 1*("." sub-domain)) / address-literal
sub-domain = Let-dig [Ldh-str]
Let-dig = ALPHA / DIGIT
Ldh-str = *( ALPHA / DIGIT / "-" ) Let-dig
I searched, and the _ character does not appear at all in 2821.
