我有一个运行 Magento 的 EC2 实例。我正在尝试设置 AWS SES，以便我们可以向客户和内部员工发送交易电子邮件，但是，我不断收到超时错误。
域名已在 SES 中设置并验证，我已配置 SMTP 用户。服务器运行 Debian 10 并使用 Sendmail 作为其 MTA。Sendmail 配置为使用 SES 的 SMTP 用户凭据发送邮件。
尝试通过命令行发送测试电子邮件得到以下结果：
/usr/sbin/sendmail -vf [email protected] [email protected]
From: [email protected]
To: [email protected]
Subject: AWS SES test email
This is a test message sent from SES using Sendmail
结果：

如果我尝试从服务器 telnet 到 SES 端点，我会得到以下信息：
telnet email-smtp.us-east-1.amazonaws.com 587

在我的 EC2 实例中，我目前已为入站和出站流量打开所有端口（我知道这不是理想的情况，但这只是暂时的，直到我能解决这个问题）。我完全不知道这里发生了什么。任何帮助都将不胜感激！
