How do you filter spam messages into a separate from RMAIL with SpamAssassin in Emacs using Emacs commands or Emacs macros.

[Don Saklad]

Thank you! I'm grateful for all the responses.

I appreciate people's efforts with the question of filtering the spam
messages into a separate file from RMAIL with SpamAssassin in Emacs

I'm looking for any outlying possibility of existing Emacs commands or
Emacs command macros that might go toward filtering.

For filtering currently in the Summary headers
I use the command Esc C-s Regexp to summarize by: debt
and use Esc C-s Regexp to summarize by: viagra
and likewise for some the other usual types.

I can't write dotfiles or write programs. I don't have other people
install dotfiles or programs that I can't tweak at this end and
usually I can't do the tweaking and have limited resources among my
friends and acquaintances.
