Programmatically set "From", Ispell dictionary and signature based on recipient

Programmatically set "From", Ispell dictionary and signature based on recipient

[Jorge P. de Morais Neto]

Hi.  I use Notmuch 0.31.2 on Emacs 27.1.50.  When I compose mail to a
mailing list, I would like Emacs to automatically set:
1. "From" header to ~"Jorge P. de Morais Neto" <jorge+list@disroot.org>~
2. Ispell dictionary to "en_US"
3. ~message-signature-file~ to "~/.signature--english" (and it should
   actually insert the corresponding file as signature)

Is there an easy way to do it, or do I have write Elisp and put it in
some Message mode hook?

Regards

An easy-ish solution would be to use message-templ (available in debian
as elpa-message-templ). I say "easy-ish" because it's a bit obscure; if
you're not using Debian you'll have to install it from source.

I think there are other solutions derived from Gnu's, but I'll let
someone with personal experience speak to those.
