在 SUSE Linux 上通过 PHP mail() 和 postfix 发送邮件时，我收到“550 发件人被管理员拒绝”错误。所有邮件都出现在 /var/mail/root 中，但未传递到电子邮件地址。

一周前，我将 /etc/postfix/main.cf 中的 inet_interfaces 从 localhost 更改为 all，然后可以通过 php 发送邮件。但是现在它停止工作了。

为了完整性，我使用这个 PHP 脚本来测试 sendmail：
<html>
<body>
<?php
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
{
//send email
$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail("[email protected]", "Subject: $subject",
$message, "From: $email" );
echo "Thank you for using our mail form";
}
else
//if "email" is not filled out, display the form
{
echo "<form method='post' action='mailtest.php'>
Email: <input name='email' type='text' /><br />
Subject: <input name='subject' type='text' /><br />
Message:<br />
<textarea name='message' rows='15' cols='40'>
</textarea><br />
<input type='submit' />
</form>";
}
?>
答案1
更改myhostname = linux.local为有用的内容。您实际存在的域名是可以接受的。
