Users that use Norton AV 2001 or some other application that uses (or sometimes uses) port 110 (for example, some other mail server on their machine) could see the message that PORT 110 is already taken by some other application.

Alternatively, you may just see error messages in your email application indicating that a connection could not be made to the mail server. For example: in Outlook Express you might see a message

There was a problem logging onto your mail server. Your User Name was rejected. Account: 'Your account name', Server: 'localhost', Protocol: POP3, Server Response: '-ERR unknown user name or bad password', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC91"

Earlier versions of ChoiceMail were not handling this problem automatically. The solution in that case was to change the POP3 port number in CM to a value other than 110 or to shut down thae other application.

If you change the POP3 port setting in ChoiceMail, you must also change your port setting for the account in your email application that connects to ChoiceMail so that they match.


In some cases, ChoiceMail can detect that the port is already in use in which case it will reconfigure the ports automatically if the configuration wizard is used and you are using Outlook, Outlook Express or Eudora. ChoiceMail is not able to detect the presence of Norton Anti-Virus 2001.

For the automatic process to work correctly the application that is using port 110 (such as your anti-virus application with email protection enabled) must already be running so that ChoiceMail can detect the conflict. In that case, ChoiceMail quietly changes the appropriate ports in the email application automatically.

If your anti-virus program gives you a choice of what email accounts to protect, you must choose those accounts BEFORE you install ChoiceMail so that ChoiceMail can pick up the correct information from your email application.

If you are using an email application other than Outlook, Outlook Express or Eudora OR if ChoiceMail was not able to detect the port conflict, then you must change the POP3 port in your email application manually. If ChoiceMail was able to detect the conflict, it will pop up a message box indicating what needs to be done and it will also indicate the new port number that needs to be set in your email application. If it could not detect the conflict, you will have to change the port in ChoiceMail as well.

Please refer to the documentation for your email application to find out how to change the ports in your email application. The changes are not always exposed in the user interface and it may be necessary to change registry entries or, in the case of Eudora, the Eudora.ini file.

In the case where the other application was not running at the time when ChoiceMail was installed, then if you subsequently run the other application after ChoiceMail has started, the other application will typically fail and indicate that the port was taken.

In this case, you will have to change the POP3 port in ChoiceMail and in your email application manually to a value other than 110. For example, try port 115, 120, 125, etc until you find one where there's no conflict.

If you are running a version of ChoiceMail older than 1.4, do NOT change the port in the other application as older versions of ChoiceMail can only connect to POP servers running on port 110. Starting with ChoiceMail 1.4, the port for each POP3 email account can be changed if required.
