Anybody can sue anyone for anything. It's a matter of whether there's a viable cause of action. If you can demonstrate that you've paid -- by proof (i.e. receipts for the money orders, etc.), then it is unlikely that your landlord will prevail at trial. Additionally, an eviction requires a court hearing. You might want to attend court to present proof that you paid your rent so that an eviction will not go on your record. You can still be evicted even though you gave notice if there's been a failure to pay rent.

If you are already moved out they cannot evict you. It sounds from your facts that you haven't lived there for 3 months, so why did you send in money? Has the landlord returned the security deposit. There are a lot of questions that need to be answered, and having an attorney in your area to answer those would be beneficial.
