HTML emails sent through rails arrive as attachment

Following problem: Whenever I try to sent a HTML-email through rails, it arrives at my googlemail-adress as an empty email with the content as an attachment.

I'm not quite sure what I'm doing wrong here.

Setup as follows:

/app/mailers/testmail.rb
class Testmail < ActionMailer::Base
  default :from => "[email protected]"
  default_url_options[:host] = '10.10.8.1'

  def email
    subject 'Willkommen!'
    recipients '[email protected]'
    from '[email protected]'
    sent_on Time.now
  end
end

/app/views/testmail/email.html.erb
<p>Dies ist eine <strong>Testmail!</strong></p>

/app/views/testmail/email.text.erb
Dies ist eine Test-Email!

This is what arrives in my Googlemail-Account:

inbox

The first email is what it looks like with with the html.erb and text.erb active, the second one with only text.erb. Ignore the username "root", that's due to a postfix rewrite because of the actual mailer being on another server (emails from the rails server get sent to the mail server which then actually mails them - not my setup ;)

And here's the raw data from the first email:

Okay, found the answer: The above version of assembling the email does NOT include the boundary neccessary. However,

mail(:to => '[email protected]')

will work and set the correct boundaries.

Dont know anything about ruby and or rails, but I do know a bit about MIME. Your top level Content-Type header should be:

Content-Type: multipart/alternative;boundary="--==_mimepart_4e79c96a1adc0_2ba53f7fe85ced90437f9"
