In VPOP3 a Connection tells VPOP3 how to connect to the Internet.
Nowadays, this will usually just be set to "connect via a router", which is the normal choice for connections over cable, xDSL, leased lines, satellite, Wifi, etc. In most cases, you will just have a single Connection, which is usually created by the Setup Wizard
To delete a Connection, select the relevant Connection, then click on the Delete button at the top-right of the Connection settings.
In some cases you may want to have multiple Connections, even if you only have one way of physically connecting to the Internet. Some examples are:
➢If you have to be able to send different mail out using different Mail Senders. Because each Mail Sender is associated with a different Connection, you need to create multiple Connections to do this.
➢If you want to have a more complex Schedule, where different Mail Collectors or Mail Senders are used at different intervals, you can create multiple Connections, and associate them with different Collectors. The Schedule tells VPOP3 when to trigger each Connection.
