163邮箱已经不支持非ssl邮件发送了，但ucenter不支持ssl发送，需要微调下

sendmail.inc.php

40行左右

} elseif($mail_setting[‘mailsend’] == 2) {

/*
*自定义ssl发送邮件
*/
$mail = new MySendMail();
$mail->setServer($mail_setting['mailserver'], $mail_setting['mailauth_username'], $mail_setting['mailauth_password'], $mail_setting['mailport'], true); //到服务器的SSL连接
//如果不需要到服务器的SSL连接，这样设置服务器：$mail->setServer("smtp.126.com", "XXX@126.com", "XXX");
$mail->setFrom($mail_setting['mailfrom']);
$mail->setReceiver($mail['email_to']);
$mail->setMail($mail['subject'], "<b>tesaaat</b>");
return $mail->sendMail($mail[message]);

邮件发送类，可以贴在最底下，搜的，测试可用。

/**
 * 邮件发送类
 * 支持发送纯文本邮件和HTML格式的邮件，可以多收件人，多抄送，多秘密抄送，带附件(单个或多个附件),支持到服务器的ssl连接
 * 需要的php扩展：sockets、Fileinfo和openssl。
 * @example
 * $mail = new MySendMail();
 * $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX"); //设置smtp服务器
 * $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX", 465, true); //设置smtp服务器，到服务器的ssl连接
 * $mail->setFrom("XXXXX"); //设置发件人
 * $mail->setReceiver("XXXXX"); //设置收件人，多个收件人，调用多次
 * $mail->setCc("XXXX"); //设置抄送，多个抄送，调用多次
 * $mail->setBcc("XXXXX"); //设置秘密抄送，多个秘密抄送，调用多次
 * $mail->addAttachment("XXXX"); //添加附件，多个附件，调用多次
 * $mail->setMail("test", "test"); //设置邮件主题、内容
 * $mail->sendMail(); 发送
