Google says Insync emails aren't safe!

I receive 100s of emails a day for years and i’ve never had an email with a warning like this before…

Has anybody else had issues with emails from Insync? Why is Google flagging them?

@Steve_G_Linux: Thanks for reporting. We can confirm this as well. I checked and found that we were not using DKIM when we sent the email yesterday. I’m not sure if it contributed to the issue but I have since enabled it.
