Rails App on Heroku Sending Email Error - ruby-on-rails-3

Question

I have my own domain name hosted on Google Apps.
My email sending works in development mode on my laptop.
In production on Heroku (cedar stack) I get this error:
Net::SMTPAuthenticationError (535-5.7.8 Username and Password not accepted. Learn more at app/controllers/applicants_controller.rb:16:in `create'):
Here is my production.rb file:
config.action_mailer.default_url_options = { :host => 'mydomain.com' }
# ActionMailer Config
# Setup for production - deliveries, no errors raised
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
config.action_mailer.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
domain: "mydomain.com",
authentication: "plain",
enable_starttls_auto: true,
user_name: "info#mydomain.com",
password: "mypassword"
}
Here is the create action in the contacts_controller:
def create
#contact = Contact.new(params[:contact])
respond_to do |format|
if #contact.save
ContactMailer.new_contact_notice(#contact).deliver
format.html { redirect_to(:root, :notice => 'Thanks, Your information was successfully sent.') }
else
format.html { render :action => "show" }
end
end
end
Here is the full section of Heroku's logs indicating the error:

I've tried some of the things I have read about this error, such as loggin into the gmail account first. I don't see anywhere in settings where it asks you if you are trying to login so I can confirm that.
Any other ideas?

It took my three days but I found the answer. I had checked and rechecked the mail settings everywhere except in the setup_mail.rb in config/initializers. That was it. Even though I had all the mail settings correct in my production.rb, application.yml and mailer files. I only had the username "name" instead of the full email address "name#domain.com".
