      That means that you can't look up smtp.google.com. Most likely because your DNS is being hijacked. This is why we don't use ping to test DNS.

        We can tell from the nslookup that you hit the right DNS server (8.8.8.8) but what we can't tell is why smtp.google.com does not exist for it. BUT if I look smtp.google.com up from here in Panama, Google DNS tells me that it does not exist either. Are you sure that the name is correct?

                The server that you are trying to reach. The only name you have here: smtp.google.com

                  Google suggests that you use this name: smtp-relay.gmail.com

                    That is specific to Google Apps. I thought he was using a personal Gmail account. That would be smtp.gmail.com

                      Oh okay, I must have misread it.

                      So just change google to gmail.

                        If he is trying to send an email to gmail... he should be sble to use the smtp-relay.gmail.com
                        That is their primary incoming MX record....
                        #dig mx gmail.com
                        gmail.com. 3599 IN MX 40 alt4.gmail-smtp-in.l.google.com.

                        gmail.com. 3599 IN MX 5 gmail-smtp-in.l.google.com.
                        gmail.com. 3599 IN MX 20 alt2.gmail-smtp-in.l.google.com.

                        #nslookup smtp-relay.gmail.com

                            Maybe that used to be okay, maybe they are all typos. But Google says it is wrong and it is Google you are trying to connect to, so I'd listen to Google here.

                              Don't read a how to. Read the official instructions first. then read a how to if you cannot figure it out.

                                            I get really really really tired of being nice to people that do not follow basic instructions.
