Using MCP with multiple rulesets

[Gray, Richard]

Hi guys,

I'm new to this list, so I apologise if I have missed something obvious
(I don't think I have)

Basically, I would like to use MCP more than once per message. I'll
illustrate:

I have a SA ruleset that contains racial insults of various forms. I
have a separate ruleset that contains pornographic references. I also
have a ruleset that represents content that I want to make sure doesn't
leave my domain. I would like my clients to be able to opt in and out of
the various filtering types.

As far as I can tell, MailScanner only calls MCP once, using all the
rulesets in the mcp directory. The best solution I have come up with is
a set of SA rules as follows (untested)

Header CLIENT_MATCH1 to=~/*@myclient.com/
Header CLIENT_MATCH2 to=~/*@myclient.com/
Meta CLIENTS_IN (CLIENT_MATCH1 || CLIENT_MATCH2)

Body BAD_CONTENT1 /some bad stuff/
Body BAD_CONTENT2 /some other bad stuff/
Meta BAD_CONTENT (BAD_CONTENT1 || BAD_CONTENT2)

Meta OPTED_IN (CLIENTS_IN && BAD_CONTENT)
Score OPTED_IN 2

Which will allow clients to opt in and out of specific rules. However,
I'm still only going to get back a single score, with no explanation of
whether it was pornographic/client_filtered etc. If I could perform any
math functions on the result that comes  back I could just ensure that
each different ruleset used only multiples of a prime number, then I
could check for the existence of the prime in the result and work it out
that way. Howver, I can't :(

Ideally, I would call MCP once for each ruleset I have, but I don't
think that's possible. Am I correct? If so, does anyone have any other
suggestions?

Many thanks.

Richard
