Once again (as I have posted this in the past here) start using Mail Washer and you can delete any email at the e-mail server level without EVER having to actually download any of it into your computer. Very easy to set up, and it will show if any of the emails waiting for you contain attachments. I swear by this program. Only receive the emails onto your computer that you want. It's also got a nice filtering system. Best of all it's free.
