Hi Phillipp,

Yes there is a way to change the port number. To do this, add a colon, and then the port number after specifying the hostname/ip address.

For example, assuming the POP3 server is 192.168.1.110, and you want to specify port 5500, the value will be: 192.168.1.110:5500.

You can make this change by hovering your mouse over Server Configuration and clicking on Manage POP3 Fetcher. In this page, click on New Account, or click on edit for an existing account.
