To select an alternative service port for SMTP services:
1. On the left menu, click SMTP. The SMTP screen appears.
2. In the Service Port section, type the desired port in the SMTP listening service
port(s) field.
3. Click Save. A message displays instructing you that the appliance must reboot in
order for this change to take effect.
4. Click OK to dismiss the message. A countdown screen appears and counts down
from 3 minutes while the appliance is rebooting. When the appliance has
rebooted, the Web console login screen appears.
5. Log on to the Web console to make any further changes.
Tip: If you are changing the SMTP service port as a security measure against hackers,
Trend Micro recommends that you use the less commonly used ports (those above
6000).
Configuring SMTP Virus Scanning
Configuring virus scanning of SMTP traffic is a three-step process. First, enable virus
scanning and then select what to scan (Target tab). Next, choose the action for Inter-
Scan Gateway Security Appliance to take when it detects a virus or other malware
(Action tab). Finally, decide whom to notify when InterScan Gateway Security Appli-
ance detects a virus or other malware (Notification tab).
Note: The procedures for configuring virus scanning for Incoming or Outgoing SMTP
traffic are the same, though the examples shown below are for SMTP Incoming
mail.
