Section 4.1.2 says:

Quoted-string  = DQUOTE *QcontentSMTP DQUOTE

It should say:

Quoted-string  = DQUOTE 1*QcontentSMTP DQUOTE

Notes:

As written, this allows for an email envelope recipient (Forward-path) with a NULL value for the local part of their address. This is a functional departure from similar wording in the preceding RFC 821, which defines quoted-string in such a way as to require at least one character that is not one of the surrounding quotation marks.
