I have all my email setup through outlook, but I was browsing Cpanel today and found out that I have like 10mb of disk space used on my mail account. I check outlook and like only 20 messages no bigger than 2kb each where saved. When I went into Horde I saw over 5000 messages of spam in some inbox I have never seen before. Is there a quick way to delete these all? How do I prevent this in the future? All the email accoutns I have setup are accessible through outlook but I have never seen these 5000 emails before.
