ruby-on-rails – 如何创建自定义邮件头

class Mailman < ActionMailer::Base
  default :from => "info@sample.com"

  def send_message(name,email,messagE)
    @name = name
    @email = email
    @message = message

    mail(:to => 'info@sample.com',:from => email,:subject => "message from the site",:headers['X-SMTPAPI'] => "category: Drip Email"
    )
  end

end

您可以使用ActionMailer的#headers方法,我已经编辑了您的示例来显示如何：

class Mailman < ActionMailer::Base
  default :from => "info@sample.com"

  def send_message(name,messagE)
    @name = name
    @email = email
    @message = message

    headers['X-SMTPAPI'] = '{"category": "Drip Email"}'

    mail(:to => 'info@sample.com',:subject => "message from the site"
    )
  end

end

或者,您可以传递哈希作为参数(对方法#headers)：

headers {"SPECIFIC-HEADER-1" => "value","ANOTHER-HEADER" => "and so..."}
