Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The remote MTA does not support ESMTP (for example, it did not understand the EHLO command 
from the Cisco IronPort appliance). 

The remote MTA supports ESMTP but “STARTTLS” was not in the list of extensions it advertised 
in its EHLO response. 

The remote MTA advertised the “STARTTLS” extension but responded with an error when the Cisco 
IronPort appliance sent the STARTTLS command. 

In this example, the 

destconfig

 command is used to require TLS connections and encrypted 

conversations for the domain “partner.com.” The list is then printed.

A certificate for example.com is used for outgoing TLS connections instead of the demonstration 
certificate that is pre-installed. You may enable TLS with the demonstration certificate for testing 
purposes, but it is not secure and is not recommended for general use.
