Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Enter an authentication username and password for the authentication profile. 

Click Finish. 

Choose Network > SMTP Routes. 

Click the All Other Domains link in the Receiving Domain column of the table. 

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. 

Submit and commit your changes.

The following events will be logged in the 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 appliance) 
times out while waiting for an authentication request.

You can configure the 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).

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 “Distributing Administrative Tasks” chapter.
