Tell your user to switch the "delete messages from server"-option on. - oliver > > Hi > The following is the exactly brief description of the problem .The version > of QPopper is 4.0.3 > > The client has down loaded all his messages, > and later when he tries to download more messages he gets all his old > mails again downloaded I dont see any relevance to this problem with the > client agents.
