Hi Everyone,
I struggled a lot trying to find a solution to the problem of my Workcentre 6027 not being able to scan to gmail. I spent countless hours, did all the tricks I could (I am pretty IT literate) and finally found a solution. So I thought I would share it with you all.
The problem was that all tutorials here were either based on firmware of other Xerox machines (which specifically allowed to tick a box with "use SSL for authentication"; the 6027 firmware does not have it) or on some third party solutions, such as SMTP2GO.
Prerequsities: your Xerox 6027 must be properly connected to the internet, so you have to be 100% sure all network settings are correct. For home-based WiFis it should be pretty simple - just scan for your home wifi network, enter the passkey, use the DHCP and that's all. For other networks - you have to find out, whether you need to use a proxy server, a static IP etc.
So what you need to do is:
1. Go to the control panel of your printer called "Centreware Internet Services". You can find out how to do it in your user manual.
2. In the CWIS go to Security -> SSL/TLS Server Communication
3. Put in the settings as in the first screenshot
4. In the CWIS go to Protocols -> Email Server
5. Put in the settings as in the second screenshot, of course supplying your gmail login name in the pixelated boxes 
6. And last, but not least - go to your google account settings and turn off 2-way authentication. Otherwise, google servers will try to ask your printer for a one time code required for each new device trying to log in to your account, which of course it is not capable of providing.
And that's all - I guarantee 100% that your scan to gmail will work :-).
Big thanks to the EO Networks - a Xerox partner in Poland (where I am from), who helped me on the part of the solution.
