If you are using a software firewall such as ZoneAlarm, you may be prompted several times for client and server permissions when you run ChoiceMail 1.5 the first time.

The three components are

1. ChoiceMail
   Requires permission to act as a client and as a server. Unless you are planning to access ChoiceMail from other machines, you can restrict server permissions to your local trusted zone.
   
2. ChoiceMail WebGate (also known as IzyMail)
   Requires permission to act as a client and as a server. The server permissions can always be restricted to just local machine access.
   
3. True Update (also known as cmupdater)
   Requires client permission only.
   

Alternatively, ChoiceMail One may just not be able to connect to the Internet and you get a socket error such
   10061 - Connection Refused
which essentially means that your firewall is silently blocking ChoiceMail One.

Note that this is NOT a problem with ChoiceMail One itself - you may need to contact your firewall vendor if you continue to see this error.

For the technically minded, by default ChoiceMail One listens for your email client using port 110, the standard POP3 port and on port 25, the standard SMTP port. It is only necessary that these ports be open on your trusted machine. If you have a hardware firewall, these ports are typically blocked from outside access.

If you only have a software firewall such as ZoneAlarm, you can configure it to only allow those ports to be opened from within your trusted network (which normally just means your own machine unless you're running a home LAN) and access will continue to be blocked from the outside world.

If you're not running a hardware or software firewall, stop what you're doing right now and go get one, even if you are not using ChoiceMail One! Running a PC these days without at least a software firewall leaves your PC at risk to serious attacks from malicious hackers.

(DigiPortal Software cannot help you to choose a firewall or provide help configuring your firewall - for the latter, please contact your firewall vendor).

Note that you can change the ports used for POP3 and SMTP between ChoiceMail and your email client if you wish - but make sure they match or else your email client will not be able to communicate with ChoiceMail.

Customers have also reported problems with ChoiceMail refusing to work or generating access violations after they convert to the retail version. This is usually due to the software firewall not giving permission to ChoiceMail. Please check your firewall permissions very carefully. More information is available here.
