Руководство Пользователя для Cisco Cisco Content Security Management Appliance M160

When you print the SMTP Routes entries, the default SMTP route is listed as 

ALL:

. You cannot delete 

the default SMTP route; you may only clear any values entered for it.

Configure the default SMTP route using the Management Appliance > Network > SMTP Routes page 
or the smtproutes command.

The Email Security appliance routes mail to local domains to hosts specified using the Management 
Appliance > Network > SMTP Routes page (or the smtproutes command). This feature is similar to 
the sendmail mailer table feature. (The SMTP Routes page and smtproutes command are an expansion 
of the AsyncOS 2.0 Domain Redirect feature.):

Use the Management Appliance > Network > SMTP Routes page (or the smtproutes command) to 
construct routes. When you create a new route, you first specify the domain or partial domain for which 
you want to create a permanent route. You then specify destination hosts. Destination hosts can be 
entered as fully-qualified hostnames or as IP addresses. You can also specify a a special destination host 
of 

/dev/null

 to drop the messages that match the entry. (So, in effect, specifying 

/dev/null

 for the 

default route is will ensure that no mail received by the appliance is ever delivered.) 

Multiple destination host entries can contain both fully-qualified hostnames and IP addresses. Separate 
multiple entries with commas. 

If one or more of the hosts are not responding, messages will be delivered to one of the reachable hosts. 
If all the configured hosts are not responding, mail will be queued for that host (does not fail over to 
using MX records).

You can define up to 10,000 routes. The final default route of 

ALL

 is counted as a route against this limit. 

Therefore, you can define up to 9,999 custom routes and one route that uses the special keyword 

ALL

. 

On the Security Management appliance, choose Management Appliance > Network > SMTP Routes.

Click Add Route.
