POP3 Services
Selecting an Alternative Service Port
The default listening port for POP3 services is 110. Administrators whose network
security policy requires the use of nonstandard ports for servers may want to change
this default.
To select an alternative service port for POP3 services:
1. On the left menu, click POP3. The POP3 screen appears.
2. In the Service Port section, type the desired port in the POP3 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 POP3 service port as a security measure against hackers,
Trend Micro recommends that you use the less commonly used ports (those above
6000).
