Junk Mail - Too Much!

I’m receiving too much junk email (much of it coming with an address like govuroh@ran.gpi.ru).
Is there a way to send all emails from .ru addresses directly to Junk?
Can I set up a rule?
Any other suggestions for weeding out these emails would be appreciated

I am sorry, but it is not possible. You can add a domain (e.g. @ran.gpi.ru) - it works OK.
