I don't know how deep I can get w/the install. It's installed on the servers and any domain owner can enable/disable and the same with the spam box. I can also do black/whitelists and probably a few other things. I don't know about actually installing it.
I'll dig around and look at what I can do WRT your suggestions.
They claim they made no changes but you know how that goes. ;)
Thanks,
Diane
