與Smtp的PHP通信

Question

我有一個郵件應用程序，每天通過cron作業發送大約5000封電子郵件（很多帳戶文件），並且在郵件發送給一個收件人時工作正常。 當我們激活BCC副本時，問題出現了，那麼應用程序開始發送直到980-1050郵件，並開始從smtp（太多收件人）收到4.5.3錯誤。如果我暫停工作並再次運行cron，那麼php進程會得到一個新的pid，並開始發送，直到達到相同的限制（980-1050郵件）。

所以我的問題是：有沒有辦法重新生成php進程ID？

如果我有能力做到這一點，那麼應用程序將發送這些郵件沒有問題。

或者我錯過了一些後綴配置？

在結束時的「錯誤」在另一功能中，BCC複印功能;在工作流程的每一次調用中，它都不會清除以前的密件副本，而是將它們相加直到達到極限。
