When forwarding a message, it should probaly add a References header field

[alejandro-colomar]

When forwarding a message, it should probably have a References header field, so that it can be correctly threaded. No?

Similar to how replies add In-Reply-To.

no, i don't think so. it isn't the same thread, just some forwarded content from another one. in fact, it can be quite disastrous when the spun off thread gets mixed up with the original one.

in cases where it's really desired, the link-threads function can be used manually. i do that on a somewhat regular basis.

one could extract and correlate message-ids from embedded messages, and create weak links (similar to those based on subjects) from that. but the UI should make it really clear that these are not regular thread links.

Hmmmm. Could be. Feel free to close the issue as WONTFIX.

I'm reopening for consideration of something I found:

thunderbird(1) does precisely this: It adds a references header, and threads the fwd with the original message.

I never had any accidents with that, and used thunderbird(1) for a long time.

Ahh, thunderbird(1) not only it adds a References; it adds both References and In-Reply-To, so it's just like a reply regarding these headers.
