Explanation:
When you create quotas and file screens, you have the option of sending e-mail notifications
to users when their quota limit is approaching or after they have attempted to save files that
have been blocked. If you want to routinely notify certain administrators of quota and file
screening events, you can configure one or more default recipients.
To send these notifications, you must specify the SMTP server to be used for forwarding the
e-mail messages.
To configure e-mail options
In the console tree, right-click File Server Resource Manager, and then click Configure
options. The File Server Resource Manager Options dialog box opens.

On the E-mail Notifications tab, under SMTP server name or IP address, type the host name
or the IP address of the SMTP server that will forward e-mail notifications.
If you want to routinely notify certain administrators of quota or file screening events, under
Default administrator recipients, type each e-mail address.
Use the format account@domain. Use semicolons to separate multiple accounts.
To test your settings, click Send Test E-mail.
