[Pdns-users] Any cure for powerdns respawning ?

[Joe Croft]

I had a similar problem. I figured out it was my mailserver doing name lookups 
on the 10s of thousands of spams it gets barraged with each day. I solved it 
by having my server use the upstream name server for name resolution. When 
you think about this, it makes sense, rarely will the name lookups from the 
mailserver be for my domains.
