Its value is

• This variable may be risky if used as a file-local variable.

Documentation:
Good candidate for GNU/Linux systems and maybe others.
You may need to modify this if your "rmail" is in a different place.
For example, I hear that in some Debian systems, it's /usr/sbin/rmail.
See feedmail-binmail-template documentation.
