I understand.
A POP client downloads stuff to a local mail file.
Typically the server is somewhere out there on the net.
The local files are on the machine the client is on.
The servers mail database is not a local file to the POP client at all.
You can argue what you like but it doesn't change the facts.

You know little about _servers_ and the connections they make.
