Thank you for your helping
but why user keeps downloading mails what he downloaded before?
I check the mail client setting and it works fine
If it is not server control, any hints about this problem
Here's one example: me. When I'm not at home, I read my email via webmail. I could, I suppose, d/l it *without* deleting from the server. Then, when I get home, I fire up t-bird, and d/l all my mail, this time deleting it.
I might assume that some folks d/l frequently, but do not delete from the server, thus saving space on their own system, but storing everything on the server.
