SMTP错误-基于PHPMailer的应用程序

php email smtp

SMTP错误-基于PHPMailer的应用程序,php,email,smtp,phpmailer,Php,Email,Smtp,Phpmailer,我基于PHPMailer编写了一个应用程序，它读取CSV并检索收件人的姓名和电子邮件地址（每个收件人都有一行），然后向他们发送电子邮件，并将电子邮件以密件传给我的工作地址（与发送电子邮件的地址相同）。它设法发送大约4-5封电子邮件，然后开始返回错误，最常见的是“SMTP connect（）失败” 我使用意大利阿鲁巴提供的SMTP服务器SMTP.Aruba.it，这是为我们公司的电子邮件设置的服务器。该公司的代表向我确认了其限制，每20分钟最多发送250封电子邮件，同时SMTP连接不超过3-4个。

我基于PHPMailer编写了一个应用程序，它读取CSV并检索收件人的姓名和电子邮件地址（每个收件人都有一行），然后向他们发送电子邮件，并将电子邮件以密件传给我的工作地址（与发送电子邮件的地址相同）。它设法发送大约4-5封电子邮件，然后开始返回错误，最常见的是“SMTP connect（）失败”

我使用意大利阿鲁巴提供的SMTP服务器SMTP.Aruba.it，这是为我们公司的电子邮件设置的服务器。该公司的代表向我确认了其限制，每20分钟最多发送250封电子邮件，同时SMTP连接不超过3-4个。每次我使用该应用程序时，我一批发送的电子邮件不到100封，并且每隔一封邮件延迟一秒钟，以避免同时打开多个SMTP连接

我打开调试并读取返回的错误，但我真的不知道如何解释它们。我在下面贴了几张

谁能帮我确定我的问题是什么以及如何修复

简言之，他们在阻止你<代码>452 4.1.1 NeKD1u00T1ustzm01eKRZu违反策略这意味着您遇到了某种策略障碍。这与您在GitHub上发布的问题相同，这里的答案相同-请与您的ISP联系。我将再次与我的ISP联系，以确定出了什么问题。谢谢。毕竟这是ISP的政策问题。我通过在XAMPP PHP中增加SMTP会话侦听时间，并在每次邮件后增加4-5秒的睡眠时间，在某种程度上避免了这种情况。进一步说，我将整个过程包装在一个循环结构中（一个有限的循环结构）：它花费了一段时间，但在通过CSV进行了几次循环之后，它成功地发送了所有电子邮件。它不适合商业用途，但非常适合我的需要。这并不漂亮，但很有效。简言之，他们在阻止你<代码>452 4.1.1 NeKD1u00T1ustzm01eKRZu违反策略这意味着您遇到了某种策略障碍。这与您在GitHub上发布的问题相同，这里的答案相同-请与您的ISP联系。我将再次与我的ISP联系，以确定出了什么问题。谢谢。毕竟这是ISP的政策问题。我通过在XAMPP PHP中增加SMTP会话侦听时间，并在每次邮件后增加4-5秒的睡眠时间，在某种程度上避免了这种情况。进一步说，我将整个过程包装在一个循环结构中（一个有限的循环结构）：它花费了一段时间，但在通过CSV进行了几次循环之后，它成功地发送了所有电子邮件。它不适合商业用途，但非常适合我的需要。虽然不漂亮，但很管用。
