Build Identifier: 

As per https://bugzilla.mozilla.org/show_bug.cgi?id=496439#c5, can I please get a parser that follows RFC 2369 (http://www.faqs.org/rfcs/rfc2369.html) as far as it can be followed so that I can use it in Bug 496439, and the compose backend can use it to make Bug 45715 do the right thing when replying to a list?

(We're about to use the same regex in two different places, which is bad not only because it's duplicated code, but also because the regex doesn't handle the allowable values of the header correctly.)


Reproducible: Always

Attachment: An email with a group in the To: header.

I grabbed the To: line straight from RFC 2822 (A.1.3. Group addresses):
To: A Group:Chris Jones <[e-mail]>,[e-mail],John <[e-mail]>;
emailed myself with it, and saved it as the attached .eml.

I'm not really sure what I thought we should do with this.  Currently, we think the message has three addresses:
A Group:Chris Jones <[e-mail]>
[e-mail]
and
John ; <[e-mail]>
but that doesn't seem quite right.

The RFC says:
In this message, the "To:" field has a single group recipient named A Group which contains 3 addresses.

If we changed it to three addresses; "Chris Jones <[e-mail]>", "[e-mail]", and "John <[e-mail]>"; I think we could justify that behaviour.  It might be better for my Reply-All patch if we could somehow treat the group as a single address or address group, which had a list of addresses within it, but I suspect that would have much larger ramifications, and so might not be worth doing.

Thanks,
Blake.

I'm not entirely sure what that last comment was doing in this bug.  Please ignore it, as I've split it off into Bug 498480.
