#3090: Mutt removes In-Reply-To header field
Comment (by vinc17):
Replying to [comment:4 pdmef]:
> IIRC In-Reply-To isn't supposed to contain only exactly some message-id
but may also contain things like "message <message-id> sent by <user> on
...". That's why mutt needs a heuristic of exactly one @ symbol to locate
the message-id. However, I don't know if clients really/still generate
something like that and how common it is in mail archives.
There are MUA's that still do such kind of things, and I still receive
messages with:
In-reply-to: <message-id> (message from <user> on <date>)
AFAIK, that's Emacs that does this. Gnus also does this, with a slightly
different format.
Also, Mutt sometimes puts several message-id's in In-Reply-To (I think,
when one replies to several messages at once).
> A fix could be to avoid writing out In-Reply-To and use References
instead which still gives the user the chance to manually adjust threads
in the editor.
That's a bad idea: some MUA's only understand the In-Reply-To header (but
this is quite old, and I don't remember which ones -- perhaps Emacs, at
least I can see that it doesn't generate a References header).
