Unmaintained and incompatible with Thunderbird 68.0+, however there is an [alternative solution](#alternative-solution). |

### Alternative solution
Borrowed from [MozillaZine: Custom headers](http://kb.mozillazine.org/Custom_headers). Archive link [1](https://archive.is/http://kb.mozillazine.org/Custom_headers), [2](https://web.archive.org/web/20190930123235/http://kb.mozillazine.org/Custom_headers). [Just in case it disappears](http://forums.mozillazine.org/viewtopic.php?f=31&t=3055133).
1. Check the value of: `mail.identity.idX.useremail` to determine which index number refers to your email account. ie Edit → Preferences → Advanced → General → Config Editor
2. Set `user_pref("mail.identity.id1.headers", "References, InReplyTo");` to create the custom headers.
3. Change the custom headers, you could use a `user.js` for this.
4. Set the values for References, you can use as many `References` as you like, just make sure they are separated with a new-line character and a space ie: `\n `.
`user_pref("mail.identity.id1.header.References", "References: <2ad46d80-c8ce-49a3-9896-16171788ac28@example.tld>\n <31ff00c2-b7cb-4063-beeb-a0bdd424c3a7@example1.tld>");`
5. Set the `In-Reply-To:` ie `user_pref("mail.identity.id1.header.InReplyTo", "In-Reply-To: <31ff00c2-b7cb-4063-beeb-a0bdd424c3a7@example1.tld>");`
6. Restart Thunderbird and send your email.
7. Comment out the above set options in your `user.js` with `/* */` and uncomment: the area to reset the values: `user_pref("mail.identity.id1.headers", "");`, `user_pref("mail.identity.id1.header.References", "");` and `user_pref("mail.identity.id1.header.InReplyTo", "");` restart Thunderbird.
