I want to use RP_MATCHES_RCVD in a meta rule. I thought I'd check its definition before I plunged in and wrote any code, so I grepped in /usr/share/spamassassin where all the original rules seem to live on my system (debian jessie). But all the hits are either for __RP_MATCHES_RCVD (which I assume is an internal rule not to be used by outsiders) or for T_RP_MATCHES_RCVD.
Since I have seen other rules in results with the T_ prefix (for example T_DKIM_INVALID) I think it must be some kind of convention with an accepted meaning. What is this conventional meaning, and how do these rules relate to the ones without the T_ prefix? -- Please *no* private Cc: on mailing lists and newsgroups Why does the arrow on Hillary signs point to the right?
