Attach io.Writer

[hasanAjsf]

I can send an email smoothly with html5 template as:

	t, _ := template.ParseFiles("template.html")
	m.AddAlternativeWriter("text/html", func(w io.Writer) error {
		return t.Execute(w, struct {
			Name    string
			Message string
			Number  string
		}{
			Name:    PushName,
			Message: caption,
			Number:  sender,
		})
	})

What I'm looking for, is instead of sending the template as the email body, I want to send it as attachement, something like:

	m.Attach(("text/html", func(w io.Reader) error {
		return t.Execute(w, struct {
			Name    string
			Message string
			Number  string
		}{
			Name:    PushName,
			Message: caption,
			Number:  sender,
		})
	})

What is the best way to do so.

Thanks
