There is a better way to go, without having to use SMTP2GO. I just spent the time on it myself as I was receiving POP errors with these instructions. See this post (http://forum.support.xerox.com/t5/Copying-Faxing-Scanning/100-working-and-easy-solution-to-Xerox-6027-Scan-to-Gmail-SMTP/td-p/177929) for gmail settings. In addition, you will need to update your Google account settings as follows:
Log in to Google, go to your account, go to "connected apps and sites" and on the right side, scroll until you see "allow less secure apps" and turn it on.
Once I did that, email finally worked!
