RMAIL Emacs sorting, filtering spam messages with spamassassin headers

[Don Saklad-2]

What newsgroup or newsgroups, listserv or listservs, web forum or
webforums, et al might have information?... about what RMAIL Emacs
existing commands there are for people who haven't programming
expertise, existing commands useful for sorting out spam messages
during a single session. Existing single session commands rather than
writing a program or dotfile for the spamassassin headers from the
system setup.

For example using Esc C-s Regexp to summarize by: rolex
C-M-s runs the command rmail-summary-by-regexp
C-M-r isearch-backward-regexp
C-M-s isearch-forward-regexp
