Because the help file instructions as far as I've read to not specifically state whether or not more than one email action can be used simultaneously, I pose the question here.
I have created an alert ruleset with a drive space alert which has three separate actions: Log the alert, send an email to one address and send an alert to a second address.
Under the Actions->Send e-mail section, the two individual email actions appear. One of which has an asterisk in front of the core server name.
I've been unsuccessful in getting the clients to alert the 2nd email address without the asterisk. Thus it appears that there is a restriction such that only one email action will be executed if multiple exists.
If anyone has had the same experience or has specific info please share it.
