在Debian上配置PHP的SMTP邮件发送可以通过多种方式实现，以下是使用sendmail和PHPMailer两种常见方法的步骤：

方法一：使用Sendmail

安装Sendmail

sudo apt update
sudo apt install sendmail

配置Sendmail 编辑Sendmail配置文件 /etc/mail/sendmail.cf 或创建一个 .cf 文件并链接到 /etc/mail/sendmail.cf。

sudo nano /etc/mail/sendmail.cf

在文件中添加或修改以下行：

define(`SMART_HOST', `smtp.yourprovider.com')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
define(`confAUTH_OPTIONS', `A p')dnl
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

重启Sendmail
```
sudo systemctl restart sendmail
```

配置PHPMailer 在你的PHP脚本中使用PHPMailer发送邮件：


use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';

$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp.yourprovider.com';                     // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->AuthType   = SMTP::AUTH_LOGIN;                        // Authentication type
    $mail->Port       = 587;                                    // TCP port to connect to; use 465 for `SMTPS`
    $mail->SMTPSecure = SMTP::ENCRYPTION_STARTTLS;         // Enable implicit TLS encryption
    $mail->Username   = 'your-email@example.com';               // SMTP username
    $mail->Password   = 'your-password';                        // SMTP password

    //Recipients
    $mail->setFrom('from@example.com', 'Mailer');
    $mail->addAddress('recipient@example.com', 'Joe User');     // Add a recipient

    // Content
    $mail->isHTML(true);                                        // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold!';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}

方法二：使用PHPMailer直接发送邮件

安装PHPMailer
```
composer require phpmailer/phpmailer
```

配置PHPMailer 在你的PHP脚本中使用PHPMailer发送邮件：


use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp.yourprovider.com';                     // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->AuthType   = SMTP::AUTH_LOGIN;                        // Authentication type
    $mail->Port       = 587;                                    // TCP port to connect to; use 465 for `SMTPS`
    $mail->SMTPSecure = SMTP::ENCRYPTION_STARTTLS;         // Enable implicit TLS encryption
    $mail->Username   = 'your-email@example.com';               // SMTP username
    $mail->Password   = 'your-password';                        // SMTP password

    //Recipients
    $mail->setFrom('from@example.com', 'Mailer');
    $mail->addAddress('recipient@example.com', 'Joe User');     // Add a recipient

    // Content
    $mail->isHTML(true);                                        // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold!';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
