Not how I read RFC 822 section 6.1! Yes a <domain-ref> is an <atom>,
but no, it can't be a <quoted-string>. [The syntactic category
"<atom> or <quoted-string>" is called <word>.] *Otherwise*
user@"[127.0.0.1]"
*would* be a valid <address>, although the <domain> part still *wouldn't*
be a <domain-literal>.
So mutt is wrong, but not quite for the reason Philip says.
Or have I misinterpreted? RFC 822 isn't exactly light bedtime reading...

Agreed. But no quoted strings!
