Following are a list of ports required by all of IceWarp services. The incoming ports below should be opened on your firewall for the IceWarp server and all server to WAN connections should be open and not limited.
For security reasons you should only open the ports for the services you require access too. If you do not use a particular service then do not open the port.
TCP 465 (SSL)
