    Is there way using NSLOOKUP to always return information from an authoritative server? It would spend things up a lot for me, if I can do it in a command line prompt. Currently I use http://www.unlocktheinbox.com/dnslookup/ , because it goes against the authoritative server. I know I can do it manually, but it’s like 4 steps for each server I look up and it’s just faster using an online took in my case.

    Do you honestly expect a person who simply uses gmail to understand all this gibberish? It is far too difficult for a non-literate computer user to fathom what I’m supposed to do to correct my gmail problem…that being the inability to send messages to known recipients.
