Junk Mail

Do any of you have a problem with getting tons of junk mail in your e-mail??? I sure do and I hate it. It seems like if I go a day without checking my e-mail, I have tons and tons of junk in there. I don't like to just delete stuff, cuz sometimes the junk mail actually appears to be real mail. Grr...I wish there was a way to sift through it more easily.
