Question

我很难让mandrill SMTP可靠地发送。或者更确切地说，每次都进行身份验证。当它进行身份验证时，电子邮件正常工作

我可以很好地运行发送脚本，然后一个接一个地连续运行2到3次。然后它没有进行身份验证。但有时它不会立即进行身份验证。

我想也许只是因为它认为我滥用它并在短时间内封锁了我。

但我可以看到，自从我开始在我的网站上使用mandrill SMTP时，其验证失败率是常规的。

尝试在域中归因的SPF和dmik文本。这没有帮助

环顾四周，我无法看到其他人遇到此问题，但按照这个速度，我当然无法将mandrill用于SMTP。

有人可以说明为什么会发生这种情况的原因吗？我的凭据是100％准确的，我不认为我发送了很多电子邮件。

使用另一个mandrill帐户在另一台服务器上遇到同样的问题。

注意：我使用的是phpmailer

我尝试每5秒触发一次电子邮件。它没有发送过10次中的3次。

1分钟后，我每10秒钟尝试一次。 10个中有8个没有发送。

Answer 1

由于它是断断续续的，它看起来肯定是一个问题。设置SMTPDebug = 3以查看整个SMTP会话。

从您给出的片面视图来看，它看起来并不像您正在使用TLS，并且在启动TLS之前通常不允许进行身份验证，但我可以看到服务器说它会执行它。我认为允许auth没有TLS作为安全漏洞，当然不是你需要允许的东西。

另外请确保您使用的是最新的PHPMailer（5.2.9 +）。
