Hopefully this will be the last of my posts asking for help on my dad's iMac. Alright, right now, I have him set up with a pop account on our ISP's server. Now, I was under the impression that with a pop account, it would delete mail from the server when you delete it locally. However, this is obviously not happening, as his mailbox is not accepting any more mail, despite the fact that he has deleted everything from his mail.app mailbox. (When we checked the web gui for his mailbox, it had all his messages still). So what gives? How do I get it to delete messages from the server?
