Cisco Cisco Email Security Appliance X1070 Troubleshooting Guide

This document describes how to change the hostname that is called in the HELO banner
associated with the Cisco Email Security Appliance (ESA).

When an end-user uses TELNET to connect to an ESA, the IP or hostname used presents an
incorrect hostname when the HELO request is issued:

Choose Network > IP Interfaces and click the name of the interface and change the Hostname
field.

Note: Remember that there is a setting in the various mail flow policies that allows you to
override the hostname form of the banner.

Submit and Commit your changes through the GUI.

Enter the interfaceconfig command and choose the configured interface you want to change the
hostname on. You will need to edit the "Hostname" field when prompted.

Currently configured interfaces:

1. Management (172.19.0.117/24 on Management: ironport.example.com)
