This is probably something I have done and my brain shut down an hour ago. When setting up SMTP according to http://docs.mattermost.com/install/smtp-email-setup.html, I click Test Connection and this error message appears.Connection unsuccessful: Failed to authenticate on SMTP server - 535 Authentication failed
My Mattermost log.[2016/05/24 02:40:39 EDT] [EROR] /api/v3/admin/test_email:SendMail code=500 rid=xanjdn9bdtfxientf79xadtdby id=b63kfq4bdfrquea17wxc85nu4o ip=MY_IP Failed to authenticate on SMTP server [details: 535 Authentication failed]

Everything is pointing to incorrect password or user. I have double and triple checked I can log into my server using these credentials. Please point me in the right direction.
Thanks
