Net::SMTPFatalError (554 Transaction failed: Missing final '@domain'

[allaire]

Using Amazon SES, I keep getting this error when exception_notification tries to send an email. My other emails are sent normally, I don't know what's wrong.

  config.action_mailer.smtp_settings = {
    :address              => 'email-smtp.us-east-1.amazonaws.com',
    :user_name            => 'USERNAME',
    :password             => 'PASS HERE,
    :authentication       => :login,
    :enable_starttls_auto => true
  }

  # Send email on exceptions
  config.middleware.use ::ExceptionNotifier,
    :email_prefix         => "[Web Exception] ",
    :sender_address       => %w{"Info" <info@lodgem.com>},
    :exception_recipients => %w{dev@lodgem.com}

Anyone has a clue?

@allaire Were you able to fix this error?

@san650 That's almost 3 years old but AFAIR this was caused by a bad smtp hostname.
