我最终自己实现了它：https :
//github.com/scorredoira/email
用法很简单：
m := email.NewMessage("Hi", "this is the body")m.From = "from@example.com"m.To = []string{"to@example.com"}err := m.Attach("picture.png")if err != nil { log.Println(err)}err = email.Send("smtp.gmail.com:587", smtp.PlainAuth("", "user", "password", "smtp.gmail.com"), m)
