Add additional email address to notification of threat

I have a series of PC's on which NOD32 is installed via remote installation using a preconfigured installation package. Is it possible to add an additional email address to the notification of threat warning? If so what is the syntax ie. are addresses separated by a "," or a ";"?
If I make a change to the installation package, do I then have to push this package back out to all the PC's in the network? Can this be done silently without disruption to users?
Should I use Eicar to test this change or is there something more appropriate to use for testing purposes?

Cheers, Brett
