SMTP error with Rails Exception Notifier plugin

Question

Working on OS X, trying to get Rails Exception Notifier plugin to send out emails. I have verified the following:

• I can successfully send email from my app
• I am creating a test error (1/0 in one of my actions).

• Current plugin installed...

  script/plugin install git://github.com/rails/exception_notification.git

• In ApplicationController...

  include ExceptionNotifiable

  local_addresses.clear

• In environment.rb...

  Rails::Initializer.run do |config|
  
  
    # ...
  
  
    config.after_initialize do
      ExceptionNotifier.exception_recipients = %w([email protected] [email protected])
      ExceptionNotifier.sender_address = %("Contact DB error" <[email protected]>)
      ExceptionNotifier.email_prefix = "[Contact DB error] "
    end
  
  
  end
  

In addition to the intentionally-created test error, I'm seeing this error on the console...

    Processing ApplicationController#index (for 127.0.0.1 at 2009-10-02 14:40:55) [GET]

    Net::SMTPFatalError (555 5.5.2 Syntax error. 3sm30577fge.12
    ):
      /usr/local/lib/ruby/1.8/net/smtp.rb:680:in `check_response'
      /usr/local/lib/ruby/1.8/net/smtp.rb:653:in `getok'
      /usr/local/lib/ruby/1.8/net/smtp.rb:631:in `mailfrom'
      /usr/local/lib/ruby/1.8/net/smtp.rb:544:in `send0'
      /usr/local/lib/ruby/1.8/net/smtp.rb:472:in `sendmail'
      /usr/local/lib/ruby/1.8/net/smtp.rb:379:in `start'
      haml (2.2.6) rails/./lib/sass/plugin/rails.rb:19:in `process'

Then it tries to send an exception notification for the SMTP error...

  Subject: [Contact DB error] application#index (Net::SMTPFatalError) "555 5.5.2 Syntax error. 3sm30577fge.12\n"

This page seems to indicate it is related to your from address. Try changing it to just [email protected].
