Working With Settings for Incoming POP Mail
Post Office Protocol (POP) is used to receive, but not send, mail. Users connect to a POP
service to retrieve all of their waiting mail. After the user has retrieved mail, it is usually
removed from the server. (A setting in the user’s mail client software determines whether it
asks the POP service to remove the user’s retrieved mail.)
The mail service has settings for requiring authenticated POP connections, changing the
POP response name, and changing the POP port number. All these settings are described in
this section.
Requiring Authenticated POP (APOP)
Your POP mail service can protect users’ passwords by requiring APOP connections. When a
user connects with APOP, the user’s mail client software encrypts the user’s password before
sending it to your POP service. Before configuring your mail service to require APOP, make
sure all users’ mail client software is able to use APOP as well.
To require APOP authentication:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the Protocols tab and select Enable POP3, if it is not already checked.
4 Click POP3 Options.
5 Select “Require APOP authentication” and click Save.
Changing the POP Response Name
You can change the DNS name that your POP mail service sends back to a user’s mail client
software when the client initiates a POP connection.
To change the POP response name:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the Protocols tab and select Enable POP3, if it is not already checked.
