使用 Django 发送电子邮件，而不是接收电子邮件

问：

我正在尝试在 Django 中实现联系表单。如果我将EMAIL_BACKEND更改为控制台而不是 smtp，它会在终端中本地工作。我已经在 Gmail 中设置了 2FA 并将其用作密码，我也正在部署到 Heroku，在那里我设置了正确的配置变量。谁能看出为什么这可能不起作用？

setting.py 文件

# https://docs.djangoproject.com/en/3.2/ref/settings/#default-auto-field

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'
DEFAULT_FROM_EMAIL = os.environ.get('EMAIL_HOST_USER')
SERVER_EMAIL = os.environ.get('EMAIL_HOST_USER')
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_USE_TLS = False
EMAIL_PORT = 465
EMAIL_USE_SSL = True
EMAIL_HOST_USER = os.environ.get('EMAIL_HOST_USER')
EMAIL_HOST_PASS = os.environ.get('EMAIL_HOST_PASS')

views.py

from django.shortcuts import render, redirect
from django.core.mail import EmailMessage, get_connection

def send_email(request):
    if request.method == "POST":

           username=settings.EMAIL_HOST_USER,

编辑：

所以我发现它正在发送电子邮件，但是食谱是输入到表单中的电子邮件，而主机电子邮件是发送它的电子邮件。我更改了这两行：

email_from = request.POST.get("email")
recipient_list = settings.EMAIL_HOST_USER

我收到服务器错误 500。但是，通过将recipient_list添加到元组中，可以修复此问题。我现在面临一个新问题，无论我在电子邮件输入中提供什么电子邮件，它都会从我那里向我发送电子邮件。
