最近发现在使用的mantisBT 1.2.7不能接收邮件通知了， 随检查测试下，果不其然，mantis的提示都很正常，就是收不到邮件，一直都是可以的，真是很是奇怪，于是就有了下面的事情，
1 、查看配置文件config_inc.php和config_defaults_inc.php主要是涉及SMTP配的
<?php
$g_enable_email_notification = ON;
$g_smtp_host = 'smtp.domain.com';
$g_smtp_usename = 'mantis@domain.com';
$g_smtp_password = 'password';
$g_phpMail_method = PHPMAILER_METHOD_SMTP; 使用PHPMailer
$g_return_path_email = ‘mantis@domain.com';
$g_from_email = 'mantis@domain.com'; 必须和登录smtp server的帐号一直，不然有些邮件服务器的配置问题会拒绝，
?>
2、使用PHPMailer做测试 （/var/www/html/mantis/library/phpmailer/）
里面有README可以参考，下面是我的测试文件内容。
<?php
require 'class.phpmailer.php';
$mail = new PHPMailer;
$mail->IsSMTP();
$mail->SMTPDebug = 1; //open debug mode, you can see clearly. 开启debug ，
// Set mailer to use SMTP
$mail->Host = 'smtp.domain.com'; // Specify main and backup server
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'mantis@domain.com'; // SMTP username
$mail->Password = 'passwod'; // SMTP password
//$mail->SMTPSecure = 'tls'; // Enable encryption, 'ssl' also accepted 根据邮件服务器情况可选
$mail->From = 'mantis@domain.com';
$mail->FromName = 'Mailer';
$mail->AddAddress('tosomeone@domain.com'); // Add a recipient
$mail->WordWrap = 50; // Set word wrap to 50 characters
$mail->IsHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->Send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
exit;
}
echo 'Message has been sent';
$mail->SetLanguage('cn', '/optional/path/to/language/directory/');
?>
保存为send_email_test.php，然后在命令行运行 或在浏览器中打开 路径
#> php send_email_test.php
可以看到和邮件服务器的交互，如下：CLIENT -> SMTP: EHLO 192.168.0.32
