bugfree安装好之后，对于邮箱发送功能，要设置一下邮件服务器。具体找到配置文件，在bugfree/include/config.inc.php
找到这几行代码：
view plaincopy to clipboardprint?
/* 8. Mail setting. */
$_CFG['Mail']['On'] = true;//开启邮箱服务
$_CFG['Mail']['FromAddress'] = "bugfree@{$_SERVER['SERVER_NAME']}";//发送邮件的邮箱地址。
$_CFG['Mail']['FromName'] = 'BugFree';//发送邮件名，不一定是邮箱地址的用户名
$_CFG['Mail']['ReportTo'] = array(); // Where
bug statistics message sened to. If empty, to all users.
$_CFG['Mail']['SendMethod'] = 'SMTP'; // MAIL|SENDMAIL|SMTP|QMAIL
/* 9. SMTP param setting. */
$_CFG['Mail']['SendParam']['Host'] = ''; // The
server to connect. Default is localhost。这里是指的邮件服务器，如果你安装bugfree上没有邮件服务器，可以使用其他邮件服务器，比如163，地址即为stmp.163.com
$_CFG['Mail']['SendParam']['SMTPAuth'] = false; // Whether or not to use SMTP authentication. Default is FALSE。这里要改成true
$_CFG['Mail']['SendParam']['Username'] = ''; // The username to use for SMTP authentication.//用户名
$_CFG['Mail']['SendParam']['Password'] = ''; // The password to use for SMTP authentication.//密码
/* 8. Mail setting. */
$_CFG['Mail']['On'] = true;//开启邮箱服务
$_CFG['Mail']['FromAddress'] = "bugfree@{$_SERVER['SERVER_NAME']}";//发送邮件的邮箱地址。
$_CFG['Mail']['FromName'] = 'BugFree';//发送邮件名，不一定是邮箱地址的用户名
$_CFG['Mail']['ReportTo'] = array(); // Where bug statistics message sened to. If empty, to all users.
$_CFG['Mail']['SendMethod'] = 'SMTP'; // MAIL|SENDMAIL|SMTP|QMAIL
/* 9. SMTP param setting. */
$_CFG['Mail']['SendParam']['Host'] = ''; // The server to connect. Default is localhost。这里是指的邮件服务器，如果你安装bugfree上没有邮件服务器，可以使用其他邮件服务器，比如163，地址即为stmp.163.com
$_CFG['Mail']['SendParam']['SMTPAuth'] = false; // Whether or not to use SMTP authentication. Default is FALSE。这里要改成true
$_CFG['Mail']['SendParam']['Username'] = ''; // The username to use for SMTP authentication.//用户名
$_CFG['Mail']['SendParam']['Password'] = ''; // The password to use for SMTP authentication.//密码
修改为如下，我使用的是自己在163上注册的邮箱地址 casilin2005@163.com
view plaincopy to clipboardprint?
/* 8. Mail setting. */
$_CFG['Mail']['On'] = true;
$_CFG['Mail']['FromAddress'] = "casilin2005@163.com";
$_CFG['Mail']['FromName'] = 'BugFree';
$_CFG['Mail']['ReportTo'] = array(); // Where bug statistics message sened to. If empty, to all users.
$_CFG['Mail']['SendMethod'] = 'SMTP'; // MAIL|SENDMAIL|SMTP|QMAIL
/* 9. SMTP param setting. */
$_CFG['Mail']['SendParam']['Host'] = 'smtp.163.com'; // The server to connect. Default is localhost
$_CFG['Mail']['SendParam']['SMTPAuth'] = true; // Whether or not to use SMTP authentication. Default is FALSE
$_CFG['Mail']['SendParam']['Username'] = 'casilin2005'; // The username to use for SMTP authentication.
$_CFG['Mail']['SendParam']['Password'] = '123456'; // The password to use for SMTP authentication.
