Is it posible that someone who sent me an email can later get into my email, how can I find my missing mail?

the only way an email can dissapear is if it had a worm or trojan horse. a worm will come into your email box like a normal email but will then start to make your computer slow down and eventually shut it down and this worm will also infect everyone on your contacts list. a trojan horse will just screw your com so bad its unfixable
Reply:Not unless the mail message contained a Trojan horse of some kind.
