Eric,
I really must disagree with you on this.
The downloaded copies of messages are stored within the e-mail client, but the messages ARE in fact left on the server - the ISP's server.
If you have any e-mail accounts that offer webmail as well as downloading, go to the ISP's webmail page after you've downloaded the messages to your e-mail client. As long as the LMOS feature is selected, you can see that the messages are still there on the server.
But I think we both know and agree on this and perhaps are reading the OP's post differently.
I believe that 'apjcs' is concerned that rather than leaving the messages on the ISP's actual server, Barca is simply storing a copy of the messages and giving the appearance that they are on the ISP's server; kind of a "virtual" server. Then he would not be able to download them to his existing mail client that he is evaluating against Barca.
I think you will agree that he can rest assured that if he has "Leave Messages On Server" checked, without any time constraint, the messages will indeed stay on his ISP's server for as long as that ISP allows them to remain there, and be available for his present e-mail client to download them also.
