Probably not if you are talking about duplicate pop3 messages where you've left them on the server. Here are the pop3 commands as I understand them (and I'm certain someone will correct my deficiencies): 1) authorization: USER, PASS, APOP (if supported) 2) transaction: a) STAT - server returns status b) LIST - server returns list of messages c) LIST msgno - server returns err or list d) RETR msgno - server returns msg e) DELE msgno - server marks message as deleted f) NOOP - server returns OK g) RSET - server unmarks any deletes and returns msg count h) UIDL msgno - if supported returns "unique-id listing" i) TOP msgno nlines - if supported - returns top nlines of msgno 3) update: a) QUIT - server deletes any marked messages and quits At least these are what used to be true. So where you are trying to leave messages on the server for a fixed amount of time such as 1 day or 2 days then it is your client which has to "remember" which messages it has already downloaded and which messages it has not. There simply is no server mechanism of which I am aware that handles this issue. The only thing the client does that updates the server is the DELE command which causes the server to mark a message as "deleted". The actually delete does not take place until the QUIT command is issued. This is why if a session is interrupted that sometimes messages marked as deleted will not in fact be deleted. But where you are leaving messages on the server for 2 days as an example then Outlook or any client has to compute that list and decide when to issue DELE commands for the messages which should be deleted.
