工作多年后网站联系表突然停止工作？

Question

您好，当我提交表单时，我收到当前错误

警告：mail() [function.mail]：SMTP 服务器响应：503 此邮件服务器在尝试发送到非本地电子邮件地址时需要身份验证。请检查您的邮件客户端设置或联系您的管理员以验证是否为此服务器定义了域或地址。在 ../.../..../ 上线 ....

在我从mail() 中删除@ 符号之前，我没有收到此错误消息，直到上个月左右它才会将其发送到我的电子邮件中。我不明白错误是什么或有什么问题请帮忙

Answer 1

这是因为您正在使用 php mail() 命令 - 然后通过 php.ini 文件中列出的 smtp 服务器发送它。

但是，当它到达该服务器时，它会说“嘿，你没有发送给我 - 你发送到一个外部地址。我不会让你”。

您可以采取以下两种方式之一来解决此问题：
1. 更改 smtp 服务器设置以允许从服务器的 IP 地址进行中继
2.设置和使用'smtp authentication'，它应该允许你发送到任何地方。这很可能已经在 smtp 服务器上设置好了，因此您只需转到 Interspire Email Marketer 设置页面并在“SMTP 服务器”部分输入适当的详细信息。
