When an email contains a "From:" line encoded with RFC 2047 which contains
characters which should, per RFC (2)822, be quoted (because it contains commas
(",") or similar characters), Mozilla doesn't decode it properly and thinks
these are two addresses.

The reverse is also true. It quotes an email address which contains a comma and
then apply RFC 2047 (which it shouldn't do).

This causes problems with MUAs which correctly encode or decode "From:" lines.

Reproducible: Always
Steps to Reproduce:
1.Send an email from Outlook Express (6.x?) with a name which contains accents
and a comma.
2.Receive it using Mozilla.
3.Try to reply.

Actual Results:
Mozilla thinks the "From:" lines contained two email addresses.

Expected Results:
It should have considered it to be one email address.

The syntax used by the other MUA (and with which Mozilla has problems) was
confirmed RFC 2047 compliant by its author, Keith Moore.

The syntax used by Mozilla when sending an email which contains accents and
commas was confirmed *not* RFC 2047 compliant by its author, Keith Moore.
