Socket Error 10054 - The virtual circuit was reset by the remote end
Error 10054 means that the connection between VPOP3 and a remote computer (eg the ISP or another computer on your LAN) was disconnected by something outside of VPOP3.
This is often caused by anti-virus software or Internet security/firewall on the VPOP3 machine but it could be any of a number of things. Any software or hardware that is sitting between VPOP3 and the ISP could be the root cause.text/html2018-11-14T10:45:49+00:00Anonymous (anonymous@undisclosed.example.com)How to Create a Connection

How to Create a Connection
There are two ways that VPOP3 can be configured to connect to the Internet. Which one you use depends on the service provided by your ISP.
Using a Permanent 'Always On' Connection
This is the most common connection method. It assumes you are connecting to the Internet via a router which is permanently connected. In this scenario VPOP3 simply needs to connect to the router so setting up VPOP3 is very simple.text/html2018-11-14T10:45:49+00:00Anonymous (anonymous@undisclosed.example.com)Restricting the number of recipients sent to
