i was running an online business a couple of years ago and one individual is now going around claiming fraud, posting up my personal information including home addresses, phone numbers, email addresses, pictures, etc. i also believe he somehow got access to my emails when this first started as many of my emails have gone missing.

since i can print a majority of the info, can i sue him for slander?

when it comes to suing for slander, will i also have to prove that i did not commit any type of fraud causing him to slander me?
