Re: Fixed order of headers in Rmail messages

[irek]

To close topic.  I managed to do exactly what I wanted to.  Now Rmail
message headers preserve order that is controlled by new list variable
`rmail-ordered-headers'.  I wrote custom function that was added around
`rmail-copy-headers' as advice.

Works well for me on old Emacs 25 and new 29 (build from master branch).
Code is available on github.  Maybe someone will like that too.  I'm
never going back to random mess.

Thanks for the help and happy coding.
