Actually, that isn't true. I've been using POP3 for years and it leaves the messages on the server if I set it that way in my program and/or app (but you can have them deleted as well if you want to). On all the other apps I have been evaluating, it keeps track of which ones have been downloaded and doesn't download them again on the same device, but allows them to be downloaded on a different device. That way I can see all the messages on all my devices. Same with Thunderbird in Windows. This is the only app that exhibits this problem. Because of this problem, I've gone with a different app. Thanks for the reply.
