Help understanding lame server error

[Scott Haneda]

I have a good deal if lame server errors in my logs, which I am not  
entirely understanding.

My server is not allowing recursions, other than to localnets.  about  
the only thing hitting it is an email server.  So I am not clear on  
why these lookups are happening, or why they are coming from all these  
other IP's
