Weird email *problem* w/ kmail fetching mail.

It appears that kmail is NOT deleting email from the server as is set to do. I find many messages on the Bellsouth website that I have downloaded to my hard drive by having Kmail get the mail in. Setup must be reasonably okay or I wouldn't get anything at all, no? I'm not running a mail server.. it's too small a group to bother doing that, everyone has a bellsouth and/or a gmail account for work and whatever for private emails.. -- j
