Nope, because both of those characters are valid e-mail address
components.  Not in the form you mention (i.e. the double quote
is not allowed in the domain part), but certainly in the local
part.

In fact this is a perfectly valid e-mail address:

"f@,'[& "@example.com

And the parser should be able to cope with them, or any other RFC
2822 compliant address.
