Net::DNS supports running background queries and using IO::Select to poll and see when an answer was received. Using Net::DNS and IO::Select , I need a script that will read a list of domains from a file, lookup the MX record for the domain ,then lookup the IN A address for the MX record returned.
## Deliverables
