952964 - Let In-Reply-To and References be disabled by a preference

Status: UNCONFIRMED

(Thunderbird :: Preferences, enhancement)

Description

[Stefan]

User Agent: 

Steps to reproduce:

Receive an email created by a 'thread agnostic' thunderbird user [1] who used the reply-to-all function on a previously received email in order to write on a new subject (thread aware users would call this 'starting a new thread') and probably save the time of selecting all the recipients individually.

[1] https://getsatisfaction.com/mozilla_messaging/topics/i_dont_like_that_threading_logic_reads_from_references_header_even_if_theres_no_in_reply_to_header

"I have some lazy friends that like to start new message threads by replying to a previous message and then editing the subject line. Google Mail displays such messages as belonging to a new thread. Thunderbird threads the message with messages that had the _older_ subject line."


Actual results:

1. The thunderbird generated In-Reply-To and References headers though this message is not intended to be a reply to thread.
2. There does not seem to be a preference which can be recommended to thread agnostic users.


Expected results:

Let In-Reply-To and References be disabled by a preference.
