php - 从 PHP 发送邮件 - 是我的错误还是邮件服务器的错误？

Question

我正在尝试从我的 PHP 脚本通过 SMTP 发送电子邮件，通过 CodeIgniter 运行。

请参阅下面的调试输出。这是否表明我的 PHP 端(无法使用 PHP SMTP 发送电子邮件)或他们端(hello: 250-parrot.email-provider.co.uk - 这对我来说意味着它已经连接到他们的服务器，因为我输入的实际 SMTP 服务器是 mail2.email-provider.co.uk，所以它似乎连接并重定向到这个 parrot 东西)。

我已确认我的 SMTP 详细信息是正确的，但它仍然说它无法验证密码 - 即使这个相同的密码在我的 native 邮件客户端中有效。

我已经更改了我的网站名称和提供商的名称(如果是我的错，我不想点名羞辱!):

可以是:

2. 服务器不允许/无法识别登录方法。
