Contact your host. Check if your mail server is working.
I was having the same problem, so i tried to install a new contact us plug in and that isnt working either, doctor vlad are you using bluehost? Thats what im using, maybe its a problem w/ them.

Have you recently updated this plugin?
No. I can not update any plugins on your host.
I discovered it happens on my Russians sites only. Any ideas?
