rb`配置。我在127.0.0.1:81上运行Gitlab，并想发送测试电子邮件
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.gmail.com"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "rafay.mir07@gmail.com"
gitlab_rails['smtp_password'] = "****"
gitlab_rails['smtp_domain'] = "localhost:81"
gitlab_rails['smtp_authentication'] = "plain"
gitlab_rails['smtp_tls'] = false
gitlab_rails['gitlab_email_from'] = 'rafay.mir07@gmail.com'
问题：
即使我已授予访问我的gmail帐户中不安全的应用程序的权限，但我仍然不断收到此错误

问题：
我的邮件服务器配置是否正确？还是我做错了其他事情？
