AP now claims the MX was Google and then changed to MXLogic.

Given that and what you say, the most likely scenario IMO is that she was getting too much spam and asked whoever was taking care of her IT to do something. They decided to front-end her email with MXLogic and it's still going to Google (but of course, we don't know for sure).

If so, the whole premise of the article (Some people use Google, but Clinton built her own server) is false.

Meanwhile, the AP thinks that Clinton's MX choices have to do with her feelings about China.

In November 2012, without explanation, Clinton's private email account was reconfigured to use Google's servers as a backup in case her own personal email server failed, according to Internet records. That is significant because Clinton publicly supported Google's accusations in June 2011 that China's government had tried to break into the Google mail accounts of senior U.S. government officials. It was one of the first instances of a major American corporation openly accusing a foreign government of hacking.
