title: SQL Server : sending Gmail failed
body: <p>I have configured Gmail in SQL Server 2008, and it sends emails properly but after 6 Jun 2022 it does not send emails and shows email status failed with the following error:</p>
  <blockquote>
  <p>The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 7 (2022-08-03T09:05:17). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required)</p>
  </blockquote>

  <li>port: 587</li>
  <li>The server require secure connection : checked</li>
