Question

我有一个邮件应用程序，通过cron作业每天发送大约5000封电子邮件（很多帐户文书工作），当邮件发送给一个收件人时正常工作。 问题出现在我们激活BCC副本时，应用程序开始发送直到980-1050邮件并开始从smtp（太多收件人）收到4.5.3错误。如果我暂停工作并再次运行cron，php进程得到一个新的pid，并开始发送ok，直到达到相同的限制（980-1050邮件）;

所以我的问题是：有没有办法重新生成php进程ID？

如果我能够做到这一点，那么该应用程序会毫无问题地发送这些邮件。

或者我可能缺少一些后缀配置？

代码的相关部分：

/**
* _Send_SmtpData
* Handles the SMTP negotiation for sending the email header and body.
*
* @param String $rcpt_to The 'receipt to' address to send the email to. This is a bare email address only.
* @param String $to The 'to' address to send this to. This can contain a name / email address in the standard format ("Name" <email@address>)
* @param String $subject The subject of the email to send.
* @param String $body The body of the email to send.
* @param String $headers The headers of the email to send.

最后＆＃34; bug＆＃34;在另一个功能，密件抄送功能;在每次调用工作流程时，都没有清理以前的bcc邮件副本，而是将它们相加，直到达到限制为止。
