Steps to reproduce:

Dear Developers, Artists,

Thank you for the marvel, art you do!

---

I tried to forward a message I received to another person.

1. Pressed Mouse Right Button on the message and selected "Forward";
2. Wrote the recipient;
3. Pressed "Send".

Same happens if forwarded "As Attachments".

Actual results:

I got error "Sending of the message failed".

When I enabled error logging and tried again, the console contained:

Seems this can happen for non-asciii msg ids.

Importing this to a folder and trying to forward it reproduces the problem

Attachment: Bug 2069136 - Handle malformed references header gracefully. r=#thunderbird-reviewers

Sending failed with "Unknown header: references" whenever the References
value contained no <...> message id: preprocessMessageIDs() returned
undefined, and the emitter can't write a value that is neither structured
nor a string.

In practice a non-ASCII message id was enough to get there. With no
structured encoder registered for References, compose fields re-emitted it
as an unstructured value via getRawHeader(), and RFC 2047 encoding hid the
angle brackets from the next parse.

(In reply to Magnus Melin [:mkmelin] from comment #3)

In practice a non-ASCII message id was enough to get there.

Thank you for the response! Indeed! The message apparently had the following headers:

From: =?UTF-8?B?0JDRgNC80LjRjw==?= <[e-mail]>
Reply-To: =?UTF-8?B?0JDRgNC80LjRjw==?= <[e-mail]>
To: [e-mail]
Message-ID: <1914028446.805.1788183797978РђСЂРјРёСЏ>

There's the "mojibake" in the ID, too, where the client had Windows-1251 set and not UTF-8.
