将表单php sendmail更改为SMTP？

我们很久以前就创建了此联系人表单，但最近我们的sendmail出现了问题，现在我需要将其更改为使用SMTP，这是我以前没有做过的。是工作量很大还是只是换了几行？欢迎任何提示

你可以在这里看到我们的整个脚本，非常简单

<?php
    if(!$_POST) exit;

    function tommus_email_validate($email) {
        return filter_var($email, FILTER_VALIDATE_EMAIL) && preg_match('/@.+\./', $email);
    }

    $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $comments = $_POST['comments'];

    if(trim($name) == '') {
        exit('<div class="error_message">You must enter your name.</div>');
    } else if(trim($name) == 'Name') {
        exit('<div class="error_message">You must enter your name.</div>');
    } else if(trim($email) == '') {
        exit('<div class="error_message">Please enter a valid email address.</div>');
    } else if(!tommus_email_validate($email)) {
        exit('<div class="error_message">You have entered an invalid e-mail address.</div>');
    } else if(trim($comments) == 'Tell us what you think!') {
        exit('<div class="error_message">Please enter your message.</div>');
    } else if(trim($comments) == '') {
        exit('<div class="error_message">Please enter your message.</div>');
    } else if( strpos($comments, 'href') !== false ) {
        exit('<div class="error_message">Please leave links as plain text.</div>');
    } else if( strpos($comments, '[url') !== false ) {
        exit('<div class="error_message">Please leave links as plain text.</div>');
    } if(get_magic_quotes_gpc()) { $comments = stripslashes($comments); }    

    $address = 'hello@basicagency.com';

    $e_subject = 'You\'ve been contacted by ' . $name . '.';

    $e_body = "You have been contacted by $name from your contact form, their additional message is as follows." . "\r\n" . "\r\n";
    $e_content = "\"$comments\"" . "\r\n" . "\r\n";
    $e_reply = "You can contact $name via email, $email (or by phone if supplied: $phone)";    

    $msg = wordwrap( $e_body . $e_content . $e_reply, 70 );

    $headers = "From: $email" . "\r\n";
    $headers .= "Reply-To: $email" . "\r\n";
    $headers .= "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type: text/plain; charset=utf-8" . "\r\n";
    $headers .= "Content-Transfer-Encoding: quoted-printable" . "\r\n";

    if(mail($address, $e_subject, $msg, $headers)) {
        echo "<fieldset><div id='success_page'><p>Thank you $name, your message has been submitted to us.</p></div></fieldset>";
    }

您可以做各种思考：

使用SMTP客户端，如PHPMAIL（）或PEAR（已更新）：

您可以使用包来处理电子邮件，例如，只需使用包含的方法来生成邮件，而不是使用
$headers
变量。下载PHPMailer并将其放置在脚本可访问的位置后，请替换以下内容：

$headers = "From: $email" . "\r\n";
$headers .= "Reply-To: $email" . "\r\n";
$headers .= "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/plain; charset=utf-8" . "\r\n";
$headers .= "Content-Transfer-Encoding: quoted-printable" . "\r\n";

if(mail($address, $e_subject, $msg, $headers)) {
    echo "<fieldset><div id='success_page'><p>Thank you $name, your message has been submitted to us.</p></div></fieldset>";
}

$headers=“From:$email”。“\r\n”；
$headers.=“回复：$email”。“\r\n”；
$headers.=“MIME版本：1.0”。“\r\n”；
$headers.=“内容类型：文本/普通；字符集=utf-8”。“\r\n”；
$headers.=“内容传输编码：引用可打印”。“\r\n”；
如果（邮件（$address，$e_subject，$msg，$headers））{
echo“谢谢$name，您的邮件已提交给我们。
”；
}

比如说：

require '/path/to/PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP();

// SMTP server details 
$mail->Host = "mail.example.com";
$mail->Port = 25;
$mail->SMTPAuth = true;
$mail->Username = "yourname@example.com";
$mail->Password = "yourpassword";

// message details 
$mail->setFrom($email, $email);
$mail->addReplyTo($email, $email);
$mail->addAddress($address, $address);
$mail->Subject = $e_subject;
$mail->Body = $msg;

// send 
if($mail->send()) {
    echo "<fieldset><div id='success_page'><p>Thank you $name, your message has been submitted to us.</p></div></fieldset>";
}
else{
    echo 'Mailer Error: ' . $mail->ErrorInfo;
}

require'/path/to/PHPMailer/phpmailerautoad.php'；
$mail=新的PHPMailer；
$mail->isSMTP（）；
//SMTP服务器详细信息
$mail->Host=“mail.example.com”；
$mail->Port=25；
$mail->SMTPAuth=true；
$mail->Username=”yourname@example.com";
$mail->Password=“yourpassword”；
//消息详细信息
$mail->setFrom（$email，$email）；
$mail->addReplyTo（$email，$email）；
$mail->addAddress（$address，$address）；
$mail->Subject=$e\u Subject；
$mail->Body=$msg；
//发送
如果（$mail->send（））{
echo“谢谢$name，您的邮件已提交给我们。
”；
}
否则{
回显“邮件错误：”。$mail->ErrorInfo；
}
您是否试图使用自己的SMTP服务器发送这些托管在另一台计算机上的邮件？我使用postfix推送电子邮件，只使用将邮件定向到那里。我确实有自己的SMTP服务器，问题是将上面的当前脚本更改为使用SMTP，而不是像现在这样使用sendmail。我怀疑您的第二个示例能否工作，尽管它在另一个问题上的投票率较高。我想您是对的（没有用户和密码）但我想展示不同的表单来实现这一点（为此链接）。我更新了我的答案使之正确。谢谢
