I suspect you have something ahead of dns in your nsswitch.conf.  The 
generic name service switch (i.e. the gethostbyname() function) is used 
for resolving the name after @ in a dig command.

Again, the name service switch is used to resolve hostnames, and it's 
using something else before trying DNS.
