Php Laravel 发送邮箱问题 Swift_TransportException

我正在使用Laravel 8.正在try 执行邮箱通知，但反复遇到以下问题.我try 并按照不同门户网站的建议更改了env文件和Mail.php文件，但没有成功.

错误:SWIFT_TransportException

预期响应代码250，但得到代码"530"，并显示消息"530错误:需要身份验证" Http://localhost:8000/forgot-password

环境文件:

MAIL_DRIVER=smtp
MAIL_MAILER=smtp
MAIL_HOST=smtp-pulse.com
MAIL_PORT=587
MAIL_USERNAME=xxx.xxx@gmail.com
MAIL_PASSWORD=5mbE7LbBtcJc
MAIL_ENCRYPTION=TLS
MAIL_FROM_ADDRESS=xxx.xxx@gmail.com
MAIL_FROM_NAME="${APP_NAME}"

Mail.php
