Unfortunately, that does not work, because of limitations of the POP3
protocol.

In POP3, there is no way to ask the server if a message was read or not.
The client has to keep track of this itself, by storing the UIDs of
mails that were retrieved before. This means that every POP3 client has
a different idea about which mails were read and which were not, because
it only knows about the mail UIDs that it stored locally.
