> There is a Thunderbird add-on called "Disable Signature" for that purpose, but it is not compatible with modern Thunderbird versions. I am guessing that its source code could also be used as inspiration.

I tried to manually apply the changes this addon made, but the strategy that add-on used no longer works for me.

After manually changing the content-type header and opening the .eml file, Thunderbird no longer displays the message text.
Executing the delete attachment action doesn't change that.
