(In reply to PS from comment #20) > What would the new behaviour be for addresses like `From: "Bugzilla@Mozilla" <bugzilla-daemon@mozilla.org>` previously used at BMO? See bug 1423440. `"xx @ yy" <person@example.com>` is frequent used, Google groups even send `From: "sunshinefox33@gmail.com" <sunshinefox33@gmail.com>`. This is also common for badly maintained mailouts where the e-mail address is used as the display name. Parts 1 & 2 refer to quotes inside the _address_, not the display name, so this affects `From: Support <it"support@mozilla.org"em@evil.com>` but not `From: "support@mozilla.org" <item@evil.com>`. See `addr-spec` in [RFC 5322 §3.4](https://www.rfc-editor.org/rfc/rfc5322#section-3.4). §3.4.1 permits a `quoted-pair`, which may contain an `@`. This bug simply suggests some (RFC-breaking) normalization that removes the quotes and any `@` within them (since it's invalid without the quotes). **That brings up an extra point for this request:** Since comments and/or folding white space (CFWS & FWS) are removed from within a `quoted-string` (see [RFC 5322 §3.2.4](https://www.rfc-editor.org/rfc/rfc5322#section-3.2.4)), Thunderbird will also have to strip those when it strips the quotes.
