Slide notes: The message Settings are the same
as what each User may choose on his or her preference profile, and these
form the default settings for Users.However, the messaging is available in
3 layers, i.e. IES Mail, e-Mail, and SMS, and all 3 levels may be supported
for your system, or else e-Mail plus IES mail, or else only IES mail. The
IES mail is always active, whereas for e-Mail and SMS the Alerter
Dispatcher must be active. Therefore, we may switch e-Mail and/or SMS
"On" or "Off".
