Thanks Dejan, I hadn't tried that. The problem with both of these is that if 
the node running MailTo or ClusterMon goes down it can't send the e-mail and 
the resource gets fenced defeating the whole purpose. Cloning ClusterMon 
worked but sends a blizzard of e-mails from each node every time an event 
occurs. I think the best answer would be for the DC to handle this sort of 
thing. I'm trying to hack together a script that runs from a cron job on each 
machine, but even if I get that to work it'll be an ugly solution and I'd 
still get at least one e-mail from each functioning node.
