  • 0

I’m sending test mail using ActionMailer. The template is being rendered and mail is being delivered fine. The only problem is the mimepart and other header data is displayed by Google in message body.

Here is the code that mails..

def testing

    mail(:to => "apoorvparijat@gmail.com",:subject => "html mailer", :content_type => "text/html") do |format|
          format.html { render 'testing' }
          format.text { render :text => "bing" }
    end
end

and Here’s the email received.

    Don’t specify :content_type => "text/html" in your mail method. Since you’re using format block, rails will automatically pick up mime type.

    MORE DETAILS:

    Try this to send out multipart email (ie. both html and text formats of email). Notice the order of formats.

    mail(:to => "apoorvparijat@gmail.com", :subject => "html mailer") do |format|
    format.text { render :text => "bing" }
    format.html { render 'testing' }
end
