To catch mail to self could be an overkill as someone could copy mail to

I was thinking a recipe to parse out the 2 parts in "From:" line:
"joe(_at_)mysite(_dot_)org" <extusr(_at_)water(_dot_)ne(_dot_)jp>
which obviously is not legitimate. That's why I mentioned using 'formail'..
See (for example) H_vars.inc in
https://rvtol.home.xs4all.nl/procmail/basic/pm/
on how to match and capture parts of the message into variables.
In there, $H_From_ and $H_From are separate captures:
the envelope-from and the header-from.
In https://rvtol.home.xs4all.nl/procmail/basic/
there is a gl_demo.rc that shows some usage.
