Fix: 'config error: mail loops back to me (MX problem?)'

To prevent receiving config error: mail loops back to me (MX problem?) errors, you need to add each virtualdomain.tld to the /etc/mail/local-host-names file and re-compile your sendmail config via make.

You have asked mail to a domain (e.g., domain.net) to be forwarded to a specific host (in this case, relay.domain.net) by using an MX record, but the relay machine doesn't recognise itself as domain.net. Add domain.net to /etc/mail/local-host-names [known as /etc/sendmail.cw prior to version 8.10] (if you are using FEATURE(`use_cw_file')) or add "Cw domain.net" to your configuration file.

See lines 11-15 of authentications_controller.rb. Excerpt shown below

def create
  omniauth = request.env["omniauth.auth"]
  authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
  # give a user account priority over authentications; therefore, 
  # merge the authentication with the signed in account.
  if current_user && authentication
    authentication.update_attribute(:user_id, current_user.id)

session[:user_id] = current_user.id

Note that Rails 3.1 uses Psych instead of Syck as its YAML parser. Stick YAML::ENGINE.yamler = "syck" at the top of config/application.rb

This would still work

login: &login
  adapter: mysql
  username: username
  password: password
 host: mysql.example.com
