首先，主要是ecmall使用的phpmailer版本太低，不支持加密连接。

然后，得对相应代码做一定调整。

1. 覆盖phpmailer

请从附件进行下载：

复制代码 代码如下:
http://cywl.jb51.net:81/201405/yuanma/ecmall_phpmailer_lib(jb51.net).zip

2. 改造lib

涉及到两个lib：mail.lib.php 、mail_quequ.lib.php

在这两个类的构造函数中，增加一个参数传递。如Mailer

复制代码 代码如下:
function __construct($from, $email, $protocol, $host = "", $port = "", $user = "", $pass = "", $SMTPSecure = false)//增加$SMTPSecure
    {
        $this->Mailer($from, $email, $protocol, $host, $port, $user, $pass, $SMTPSecure);
    }

    function Mailer($from, $email, $protocol, $host = "", $port = "", $user = "", $pass = "", $SMTPSecure = false)
....

MailQueue中同理。

3. 封装调用函数

global.lib.php 约300行

function &get_mailer()中增加一行：

复制代码 代码如下:
$secure   = Conf::get("email_ssl");//增加这一行
$mailer = new Mailer($sender, $from, $protocol, $host, $port, $username, $password, $secure);//同时传递参数

4. 调整后台email设置界面，增加相关设置项

后台模板：setting.email_setting.html 增加一个配置项

复制代码 代码如下:
<tr>
    <th class="paddingT15">邮件服务器加密方式:</th>
    <td class="paddingT15 wordSpacing5">
       {html_radios name="email_ssl" options=$email_ssl checked=$setting.email_ssl}
        <label class="field_notice">此功能要求您的php必须支持OpenSSL模块, 如果您要使用此功能，请联系您的空间商确认支持此模块</label>
    </td>
</tr>

同时，修改邮件测试的参数传递

复制代码 代码如下:
<script type="text/javascript">
$(function(){
    $("#send_test_email").click(send_test_email);
});
function send_test_email(){
    var email_type = $("input[name="email_type"]:checked").val();
    var email_ssl = $("input[name="email_ssl"]:checked").val();//增加这一行
    $.ajax({
        type:"POST",
        url:"index.php",
        data:"app=setting&act=send_test_email&email_type="+email_type+"&email_host="+$("#email_host").val()+"&email_port="+$("#email_port").val()+"&email_addr="+$("#email_addr").val()+"&email_id="+$("#email_id").val()+"&email_pass="+$("#email_pass").val()+"&email_test="+$("#email_test").val()+"&email_ssl="+email_ssl,
        dataType:"json",
        success:function(data){
            if(data.done){
            alert(data.msg);
            }
            else{
                alert(data.msg);
            }
        },
        error: function(){alert("{$lang.mail_send_failure}");}
    });
}
</script>

然后还需要修改setting.app.php

复制代码 代码如下:
/**
     *    EMAIL 设置
     *
     *    @author    Hyber
     *    @return    void
     */
    function email_setting()
    {
        $model_setting = &af("settings");
        $setting = $model_setting->getAll(); //载入系统设置数据
        if (!IS_POST)
        {
            $this->assign("setting", $setting);
            $this->assign("mail_type", array(
                MAIL_PROTOCOL_SMTP  => Lang::get("smtp"),
                MAIL_PROTOCOL_LOCAL => Lang::get("email"),
            ));
　　　　　　　　//增加
            $this->assign("email_ssl", array(
=> Lang::get("no"),
 => "SSL",
 => "TLS",
            ));
            $this->display("setting.email_setting.html");
        }
        else
        {
            $data["email_type"]     = $_POST["email_type"];
            $data["email_host"]     = $_POST["email_host"];
            $data["email_ssl"]       = $_POST["email_ssl"];//增加
            $data["email_port"]     = $_POST["email_port"];
            $data["email_addr"]     = $_POST["email_addr"];
            $data["email_id"]       = $_POST["email_id"];
            $data["email_pass"]     = $_POST["email_pass"];
            $data["email_test"]     = $_POST["email_test"];
            $model_setting->setAll($data);

            $this->show_message("edit_email_setting_successed");
        }
    }

以及测试邮件方法。

复制代码 代码如下:
function send_test_email()
    {
        if (IS_POST)
        {
            $email_from = Conf::get("site_name");
            $email_type = $_POST["email_type"];
            $email_host = $_POST["email_host"];
            $email_ssl = $_POST["email_ssl"];//增加
            $email_port = $_POST["email_port"];
            $email_addr = $_POST["email_addr"];
            $email_id   = $_POST["email_id"];
            $email_pass = $_POST["email_pass"];
            $email_test = $_POST["email_test"];
            $email_subject = Lang::get("email_subjuect");
            $email_content = Lang::get("email_content");

            /* 使用mailer类 */
            import("mailer.lib");
            $mailer = new Mailer($email_from, $email_addr, $email_type, $email_host, $email_port, $email_id, $email_pass, $email_ssl);//增加
            $mail_result = $mailer->send($email_test, $email_subject, $email_content, CHARSET, 1);
            if ($mail_result)
            {
                $this->json_result("", "mail_send_succeed");
            }
            else
            {
                $this->json_error("mail_send_failure", implode(" ", $mailer->errors));
            }
        }
        else
        {
            $this->show_warning("Hacking Attempt");
        }
    }

tls方式没有测试过。
