Spam Mails

This is absurd! I got 30,000 emails and still counting, most of which are spam mails! This is unbelievable!!! I started downloading my mails this morning and until now, I haven't even deleted half of it. This is such a waste of time. Argh!!! My email browser has timed out because it can't handle the number anymore. I have no other choice but to download it all through webmail which I'm doing now and is taking decades to delete! Rats!!!
