I am new to Macs and not sure if I need to do this through my Mac or through my server, but I got a notice from my server that I was over quota in my e-mail on the server. I had assumed that when I emptied my mailbox that the e-mail was also removed from the server, but obviously not. Can someone tell me how to see to it that the e-mail is automatically removed without having to return to the server and eliminate the e-mails?
