我的 django 应用程序无法发送电子邮件。在我的电子邮件中，安全性较低的应用程序已打开，并且我已解锁验证码。我被困住了，我不知道缺少什么。任何帮助将不胜感激。

# Create your views here.

def contact (request):  
    if request.method == "POST":
        sender_name = request.POST.get('sender-name',False)
        sender_number = request.POST.get('sender-number',False) 
        sender_email = request.POST.get('sender-email',False)
        sender_subject = request.POST.get('sender-subject',False)
        message = request.POST.get('message',False)

        send_mail (
            sender_name, 
            sender_number,
            sender_email,
            ['***********@gmail.com'],
            sender_subject,
            message,
            )

        return render (request,'shield_sec/contact.html', {'sender_name': sender_name}) 
    else:
        return render (request,'shield_sec/contact.html', {})

我怀疑问题可能出在我的 settings.py 中，但一切看起来都很好。
