[Xymon] Sanity checking my alert config

In alerts.cfg, I have this:

HOST=* COLOR=red,purple SERVICE=msgs MAIL $ADMINMAIL HOST=* COLOR=red,purple IGNORE SERVICE=msgs MAIL $ADMINMAIL RECOVERED

My goal with this is to see alerts for purple and red statuses for all tests, and then get recovery alerts for all tests except msgs. Did I do the config right for that?

I would also like to see if I can get a legend for the alerting grid in the "info" page. Here's a screenshot showing what the above config produces:

I'd like to know what "(R)" and "(S)" mean, and what the line where the email address is blue means.

Thanks, Shawn
