如果我使用PHPmailer發送單線消息,它將消除任何錯誤。PHPmailer數據不被服務器接受:421
但如果我發送大消息(10行),我得到以下錯誤::。
SMTP -> FROM SERVER:250 2.5.0 Address Ok.
SMTP -> FROM SERVER:250 2.1.5 <toaddress>@gmail.com OK.
SMTP -> FROM SERVER:354 Enter mail, end with a single ".".
SMTP -> FROM SERVER:421 4.4.2 Timeout while waiting for command.
SMTP -> ERROR: DATA not accepted from server: 421 4.4.2 Timeout while waiting for command.
SMTP Error: Data not accepted.
