[Error]Notify members via email (will slow down posting)

[farmerinchina]

If ticking the option 'Notify members via email (will slow down posting)' when posting on wire, I got the following error:

Fatal error: Cannot redeclare class EkinMailer in /public_html/wp-includes/mail-inc.php on line 14

EkinMailer is a class to correct the bug of mail system of WPMU, which has the source code below:

<?php

require("class-phpmailer.php");
class EkinMailer extends PHPMailer {

var $Mailer = "smtp";
var $CharSet = "utf-8";
var $From = "xxx";
Var $FromName = "xxx";
var $Host = "xxx";
var $Port = 25;
var $SMTPAuth = true;
var $Username = "xxx";
var $Password = "xxx";
var $WordWrap = 75;

}

?>

If I use the default mail system of WPMU, only hotmail can receive the activate email when registrating, so I google the EkinMailer to fix it. But now, when starting to use Buddypress, the above error occurs when posting.

Kindly advise how to fix this bug eventually. Thanks a lot!

WPMU version : 2.6.1

Please bring this up on WPMU trac, BuddyPress is not handling the mail functionality, that's WPMU's job.
