From: "Vince Sabio" <vince-isoc(_at_)vjs(_dot_)org>
To me, this means that the local-part of an address may either be
quoted or may contain dot-atoms, but may not contain embedded quoted
substrings. For example, consider the following address local-parts:
VALID: vince.sabio
VALID: "vince sabio" (deprecated, but nonetheless valid)
NOT VALID: vince."human mail server".sabio
Is my interpretation of 3.4.1 correct, or am I reading something
wrong here?
That's how I interpret both the text and the ABNF of 3.4.1.
If you want to put quotation marks in the local-part, you have to use a
quoted-string containing quoted-pairs:
VALID: "vince.\"human mail server\".sabio"
NOT VALID: vince."human mail server".sabio
