php mail()不从不同的域发送电子邮件

Question

我正在使用php的邮件功能发送电子邮件。问题是，来自不同域的电子邮件无法发送。只有来自我的域的电子邮件才会发送。例如，当我从username@mydomain.com发送一封电子邮件时，它就被发送了。当我使用from as username@yahoo.com或username@gmail .com发送电子邮件时，不会发送电子邮件。

当电子邮件被发送时，它们最终会出现在垃圾邮件部分。

需要哪些标头才能绕过此限制？或任何其他解决方案。

谢谢。

Answer 1

这取决于您的SMTP服务器。这可能会阻止垃圾邮件流出。

Answer 2

您可以使用PEAR邮件功能http://pear.php.net/package/Mail .By使用此功能您可以从交换服务器发送电子邮件如果您使用sendmail server.But，则可以使用以下code.The下面的代码将不适用于microsoft exchange server

希望能对你有所帮助。

<?php
//new function
$to=//receipent email addressaddress;
$message=//Message;
$nameto = "Name of receipent";
$from = "abc@example.com";//sender address

}

if(authSendEmail($from, $namefrom, $to, $nameto, $subject, $message))
{echo "send";}
else{echo "failed";}

尝试在mail()函数中添加第五个参数：

mail($to,$subject,$message,$headers,"-f ".$from);

注意：$from必须与您在邮件头中指定的“发件人”电子邮件地址相似。
