On most mail systems, as I understand it, procmail *is* the delivery agent.
Sendmail calls procmail to write the mail to the final mailbox.

Grep your sendmail.cf file, and you'll likely see a procmail path in there.

Go back to your original rule:

Procmail sees destinations with a trailing slash as maildir destination
directories.  If you put a filename there instead, it will write it as
an mbox file.

         * ^rule: stuff at mail.list

If you're using mbox anyway, you don't need a directory for each
rule, so this will do:

         * ^rule: stuff at mail.list
