Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Click the All Other Domains link. The Edit SMTP Route page is displayed. Enter the name of the 
Destination Host for the SMTP route. This is the hostname of your external mail relay used to deliver 
outgoing mail.

Select the outgoing SMTP authentication profile from the drop-down menu. Click the Submit button

Commit your changes.

The following events will be logged in the Cisco IronPort mail logs when the SMTP Authentication 
mechanism (either LDAP-based, SMTP forwarding server based, or SMTP outgoing) is configured on 
the appliance: 

[Informational] Successful SMTP Authentication attempts — including the user authenticated and 
the mechanism used. (No plaintext passwords will be logged.) 

[Informational] Unsuccessful SMTP Authentication attempts — including the user authenticated 
and the mechanism used. 

[Warning] Inability to connect to the authentication server — including the server name and the 
mechanism. 

[Warning] A time-out event when the forwarding server (talking to an upstream, injecting Cisco 
IronPort appliance) times out while waiting for an authentication request.

You can configure the Cisco IronPort appliance to use an LDAP directory on your network to 
authenticate users by allowing them to log in with their LDAP usernames and passwords. After you 
configure the authentication queries for the LDAP server, enable the appliance to use external 
authentication on the System Administration > Users page in the GUI (or use the 

userconfig

 command 

in the CLI).

To configure external authentication for users, complete the following steps:

Create a query to find user accounts. In an LDAP server profile, create a query to search for user 
accounts in the LDAP directory.

Create group membership queries. Create a query to determine if a user is a member of a directory 
group.

Set up external authentication to use the LDAP server. Enable the appliance to use the LDAP server 
for user authentication and assign user roles to the groups in the LDAP directory. For more information, 
see “Adding Users” in the Cisco IronPort AsyncOS for Email Daily Management Guide.
