Yes, Profihost sent me one recently that looked very similar.
Fortunately, I use OutboundBindAddress, so I knew it was
(very likely to be) exit traffic.

You can:
* do nothing
* respond and ask for verification that they want your exit
   to block their site, but explain that they need to block
   all Tor Exits for the traffic to stop
* add exit policy entries to block each of the mentioned
   IPs and ports
* block port 22 on your exit

I'll be doing nothing.

You should consider your provider's reaction, because they
may want you do something about the complaint, even if
it's something ineffective.
