sendmail 和 gmail 未收到

我尝试使用 PHP 脚本通过 sendmail (Debian 8) 发送邮件。它确实有效，但只有 gmail 不起作用。

从 root 发送邮件，我收到此消息

我找不到在 sendmail 中更改 127.0.0.1 的位置。我确实在 DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp, Addr=5.xxxx') 中进行了更改，但没有生效。

我应该在哪里更改 sendmail 中的哪些内容才能将邮件发送到 gmail？

我真的不明白如何在这个页面上做事： https://support.google.com/mail/answer/81126?p=ipv6_authentication_error&rd=1#authentication

答案1

正如消息告诉您的那样，2001：41d0：e：4c8：：1 没有设置反向 DNS 条目。

要解决此问题，您需要将此的反向 DNS 设置为正确的主机名值，该值也会解析为相同的 IP 地址。您可以在 OVH 管理面板中执行此操作。
