推荐答案
Gmail不适合测试。他们收到邮件一段时间后禁止你 - imho 15min。
使用本地邮件服务器，如免费的https://www.hmailserver.com/
（设置中还有禁止选项，可以轻松关闭！）
Gmail is not good for testing. They ban you after you have received mails for a certain time - imho 15min.
Use a local mailserver like the free https://www.hmailserver.com/
(There is also a ban option in the setting, which can be switched off easily!)
