From this excellent JavaMail tutorial:

Just because a flag exists doesn't mean the flag is supported by all mail servers/providers. For instance, besides deleting messages, the POP protocol supports none of them. ... To find out what flags are supported, ask the folder with getPermanentFlags().

If you're using POP3 then you need to do that in your client code.

The client needs to keep track of which messages have been looked at, possibly by making a note of their subject, sender and time, or some other uniquely identifying characteristic (look through the message headers - there may be a message ID or something similar that you can use). This needs to be stored on the client somewhere, so that it is available next time the client is run.
