I believe so. A close reading of sections 3.2.2, 3.2.3, and 3.2.4 of RFC
5322 suggests that there is nothing wrong with the header.
I would guess that because "," is a special that it cannot be included
as "atom text" which necessitates the quoting. Furthermore, it is stated
that:
A quoted-string is treated as a unit. That is, quoted-string is
identical to atom, semantically. Since a quoted-string is
allowed to contain FWS, folding is permitted.
And further:
As stated earlier, the "\" in any quoted-pair and the CRLF in
any FWS/CFWS that appears within the quoted-string are
semantically "invisible" and therefore not part of the
quoted-string either.
Good luck telling this to the administrator of the server that rejected
the email.
