I've been using Redmine for 3.5 years using my office365 account as the smtp server.  I have recently purchased a new domain and move my office365 account from GoDaddy to Microsoft.  I have updated the configuration.yml to reflect the changes, but when I attempted to send emails from Redmine I was getting an authenication error.  I researched any additional settings as well as attempted to use my gmail account, but still was getting an authenication error.  I opened the Turnkey Configuration console and went through the advanced menu settings.  In the mail relay settings, I don't remember changing anything, but now when I attempt to send a test email, I get the following: An error occurred while sending mail (hostname "localhost" does not match the server certificate).  Nothing I change will get rid of this error.  I have done the 'deconfigure", but still the same error.  Is there file that was automatically written to or file that can be erased.

Here is my current configuration.yml file:

production:
 email_delivery:
 delivery_method: :smtp
 smtp_settings:

  address: smtp.office365.com
  enable_starttls_auto: true
  port: 587
  domain: mydomaintech.com
  authentication: :login
  user_name: help@mydomaintech.com
  password: H0NotRealPasswordCR

default:
  wkhtmltopdf_exe_path: '/usr/local/rbenv/shims/wkhtmltopdf'

Thanks for looking and any help that you can provide.
