共计 12625 个字符，预计需要花费 32 分钟才能阅读完成。

First, download PHPmailer (http://sourceforge.net/projects/phpmailer/files/phpmailer%20for%20php5_6/)
1. Upload PHPmailer files
Only 3 files are essential:
CODE: SELECT ALL
class.phpmailer.php
class.pop3.php
class.smtp.php

Upload these 3 files to /system/library

2. Include PHPmailer in startup.php
Open /system/startup.php

Find:
CODE: SELECT ALL
require_once(DIR_SYSTEM . ‘library/mail.php’);

After, add:
CODE: SELECT ALL
require_once(DIR_SYSTEM . ‘library/class.phpmailer.php’);

3. Replace built-in mail function with PHPmailer in mail.php
Open: /system/library/mail.php

Find:

4. Do the same with Contact Form
Open: /catalog/controller/information/contact.php

Find:

[php]
$mail = new Mail();
$mail->protocol = $this->config->get(‘config_mail_protocol’);
$mail->parameter = $this->config->get(‘config_mail_parameter’);
$mail->hostname = $this->config->get(‘config_smtp_host’);
$mail->username = $this->config->get(‘config_smtp_username’);
$mail->password = $this->config->get(‘config_smtp_password’);
$mail->port = $this->config->get(‘config_smtp_port’);
$mail->timeout = $this->config->get(‘config_smtp_timeout’);
$mail->setTo($this->config->get(‘config_email’));
$mail->setFrom($this->request->post[’email’]);
$mail->setSender($this->request->post[‘name’]);
$mail->setSubject(sprintf($this->language->get(’email_subject’), $this->request->post[‘name’]));
$mail->setText(strip_tags(html_entity_decode($this->request->post[‘enquiry’], ENT_QUOTES, ‘UTF-8’)));
$mail->send();
[/php]

Replace with:

[php]
$mail = new PHPMailer(true); //New instance, with exceptions enabled

$body = strip_tags(html_entity_decode($this->request->post[‘enquiry’], ENT_QUOTES, ‘UTF-8’));
$body = preg_replace(‘/\\\\/’,”, $body); //Strip backslashes

$mail->IsSMTP(); // tell the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = $this->config->get(‘config_smtp_port’); // set the SMTP server port
$mail->Host = $this->config->get(‘config_smtp_host’); // SMTP server
$mail->Username = $this->config->get(‘config_smtp_username’); // SMTP server username
$mail->Password = $this->config->get(‘config_smtp_password’); // SMTP server password

//$mail->IsSendmail(); // tell the class to use Sendmail

$mail->AddReplyTo($this->config->get(‘config_email’));

$mail->From = $this->request->post[’email’];
$mail->FromName = $this->request->post[‘name’];

$to = $this->config->get(‘config_email’);

$mail->AddAddress($to);

$mail->Subject = sprintf($this->language->get(’email_subject’), $this->request->post[‘name’]);

$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->WordWrap = 80; // set word wrap

$mail->MsgHTML($body);

$mail->IsHTML(true); // send as HTML

$mail->Send();
[/php]

At last but not least, do not forget to configure your mail section in admin!
Login to admin and go to System > Settings > Mail
Mail Protocol: SMTP
SMTP Host: localhost
SMTP Username: info@mydomain.com
SMTP Password: *******
SMTP Port: 25
SMTP Timeout: 5
Alert Mail: Yes
Additional Alert E-Mails: additional@gmail.com

Note: I set host to localhost as I use info@mydomain.com. If you use Gmal/Yahoo/etc, set it to proper SMTP server.

Important: Im not an experienced in php coding. There might be some flaws in this code as I don’t understand it fully (hey, at least I’m being honest! ).
Example of potential flaw: in 3rd step the replacement code includes this line:
CODE: SELECT ALL
if (strpos($this->hostname,’gmail’))
I have no idea what is the purpose of gmail part! Please advise

I hope it works for you too!
