I used to rely on the Change quote and reply format to customise the header in the replied emails. So it would turn this:
On 01/01/2005 at 10:00, support@example.com wrote:
Some email
Into this:
---- Original message -----
Subject: something
From: support@example.com
To: recipient@example.com
Date: 01/01/2005Some email
But in recent versions of Thunderbird this add-on has been disabled for being out-dated and no update is available.
Is there currently a way, native or otherwise, to do something similar?
