postfix-mta - Compute Engine 上的 Sendgrid 无法正常工作

Question

我使用 sendgrid 设置 Postfix，就像这里的指南一样:https://developers.google.com/compute/docs/sending-mail?hl=en#postfixsendgrid

但它不起作用。当我运行测试命令时:

printf 'Subject: test\r\n\r\npassed' | /usr/sbin/sendmail myemail@gmail.com

我在日志中收到此错误:

如果您使用的是 debian，则还需要安装 libsasl2-modules:

apt-get install libsasl2-modules

这解决了我的问题。
