问题描述

我已经用gmail帐户设置了SMTP服务器。直到几天前，它的工作情况还不错。当我检查日志时，在其中找到以下条目：

I have set up SMTP server with gmail account. It was working fine till few days back. When I checked the logs I found below entry in it:

SMTP Error: 454 4.7.0 Too many login attempts, please try again later.

我已经重新启动了SMTP服务两次。我已经检查了使用此链接。一切都与我们设置的相同。我已重新启动SMTP服务器&

I have restarted SMTP service twice. I have checked the configuration that was set up using this link. Everything is same as we have set up. I have restarted the SMTP server & the machine too.

我已经检查了两步验证设置。未启用。我已经检查了安全性较低的应用程序设置，并根据建议在此处。

I have checked for 2 step verification settings. It is not enabled. I have checked for "less secure" apps settings and it is set to Enabled as suggested here.

我已按照建议检查了已启用的应用程序此处使用以下链接。

I have checked apps enabled as suggested here using below link.

但未添加任何应用。谁能建议我需要的东西？

But no apps are added. Can anyone suggest anything that I need to look for? Thanks in advance.
