Hi,
For the lack of a dedicated Thunderbird mailing list, I am forced to
ask here.
I am using Debian Buster. I have set up a custom header (X-no-archive)
using this guide:
https://www.lifewire.com/arbitrary-custom-heading-email-thunderbird-1173089
It works fine, but I have to click on the double arrows (top right)
all the time and then type "Yes"
Is there a way to have this header with a default value "Yes" attached
to all outgoing messages automatically?
I have no experience using Thunderbird, and next-to-no experience
using any mozilla product whatsoever. Caveat lector.
Sometimes I read stuff here, though:

Today the kb.mozillazine.org server seems to be having some trouble,
but there is this page at the wayback machine:

Thunderbird 1.5 added the ability to add a custom header to every
message you send using a identity (From: address), without having to
do anything when composing the message. It requires at least two
preferences be added to prefs.js. One preference lists the name of
the preferences that define each custom header for that
identity. The others specify the custom header and the value. For
example:
user_pref("mail.identity.idN.headers", "archive");
user_pref("mail.identity.idN.header.archive", "X-No-Archive: yes");
where 'N' is the appropriate id number. Notice that while the custom
header is X-No-Archive its defined using a different name. You could
add two custom headers for id3 using:
user_pref("mail.identity.id3.headers", "archive, gazette-tag");
user_pref("mail.identity.id3.header.archive", "X-No-Archive: yes");
user_pref("mail.identity.id3.header.gazette-tag",
"X-gazette-tag: Bubba");
You can look in prefs.js or use
Tools -> Options -> Advanced -> General -> Config Editor
to find the number of the identity. The simplest way to find the id
value might be to search for the email address.
mail.identity.id1.useremail for example contains my default email
address.
My guess is it is probably not possible, but you never know. Thanks.
Good luck.
