You can create email user objects for use with SMTP Client policies. An email user object can be a list of users or an entire domain. For more information about email user objects, see “Email User Objects” .
|
Step 1
|
In the navigation pane on the left side, click Application Firewall, and then click
Email User
Objects
.
|
|
Step 2
|
In the Email User Objects screen, click
Add New Email User Object
.
|
|
Step 4
|
For Match Type, select
Exact Match
or Partial Match
. Use Partial Match when you want to match on the domain only. To match on individual users, select Exact Match.
|
To match on a domain, type @ followed by the domain name, for example: @sonicwall.com . To match on an individual user, type the full email address, for example: jsmith@sonicwall.com . Repeat this step until you have added as many elements as you want.
Alternatively, you can click Load From File to import a list of elements from a text file. Each element in the file must be on a line by itself.
By defining an email user object with a list of users, you can use Application Firewall to simulate groups.

Under Bandwidth Management, to manage outbound bandwidth, select the
Enable Egress
Bandwidth Management
checkbox, and optionally set the Available Interface Egress
Bandwidth (Kbps)
field to the maximum for the interface.
|
|
•
|
Under Bandwidth Management, to manage inbound bandwidth, select the
Enable Ingress
Bandwidth Management
checkbox and optionally set the Available Interface Ingress
Bandwidth (Kbps)
field to the maximum for the interface.

If you plan to use this custom action for rate limiting rather than guaranteeing bandwidth, you do not need to change the Guaranteed Bandwidth field.
|
Step 7
|
For
Maximum Bandwidth
, optionally enter a value either as a percentage or as kilobits per second. In the drop-down list, select either %
or Kbps
