<code>SMTP server error: 5.7.1 : Relay access denied </code>
登陆服务器用mail -s "test" *****@qq.com 测试过smtp服务器是可以发送邮件的。为什么用PHP写的函数就被拒绝了呢?这段函数以前是起作用的,而且丝毫没动过。
<code>public function SendMail($address,$title,$message) { vendor('PHPMailer.class#phpmailer'); $mail=new PHPMailer(); // 设置PHPMailer使用SMTP服务器发送Email $mail->IsSMTP(); // set HTML $mail->ishtml(true); // 设置邮件的字符编码,若不指定,则为'UTF-8' $mail->CharSet='UTF-8'; // 添加收件人地址,可以多次使用来添加多个收件人 $mail->AddAddress($address); // 设置邮件正文 $mail->Body=$message; // 设置邮件头的From字段。 $mail->From=C('MAIL_ADDRESS'); //设置发件人名字 $mail->FromName=C('MAIL_SENDER'); // 设置邮件标题 $mail->Subject=$title; // 设置SMTP服务器。 $mail->Host=C('MAIL_SMTP'); // 设置为“需要验证” $mail->SMTPAuth=true; // 设置用户名和密码。 $mail->Username=C('MAIL_LOGINNAME'); $mail->Password=C('MAIL_PASSWORD'); // 发送邮件。 $mail->Send(); return $mail; } </code>

PHPMailer会使用那些经常被ISP方禁用的函数,如popen,你可以用phpinfo()查询一下disable_functions的值,看看是否关多了function。
问题解决了,感谢大家的回答。最后看error发现是因为重启sasl后会把/var/run/saslauthd变成710。所以需要chmod.
我是用thinkphp框架的 ,也起到了这种问题 可以帮忙解决一下吗

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.
