The Directed-Email Action is similar to the E-mail Message Action in that it sends SMTP email messages with the alert text in the message body. What makes it different is that the monitor that calls this action specifies who the emails should be sent to (instead of the email address being set at configuration time).
This action is typically used with monitors where end users might need to receive alerts (like the various Quota monitors for example).
Like the E-mail Message Action, the Directed-Email Action also supports Message Digests. Message Digests combine all messages that arrive within a short amount of time for a email address into a single message.
The SMTP server settings (which are global to all email actions) are also used by this action to send the message. To change them, go to an E-Mail Message action and change them there.
