check this out:

functions.php line 3009:

/**

 */
function sed_mail($fmail, $subject, $body, $headers='', $additional_parameters = null)
{
	global $cfg;

	if(empty($fmail))
	{
		return(FALSE);
	}
	else
	{
		$headers = (empty($headers)) ? "From: \"".$cfg['maintitle']."\" <".$cfg['adminemail'].">\n"."Reply-To: <".$cfg['adminemail'].">\n" : $headers;
		$body .= "\n\n".$cfg['maintitle']." - ".$cfg['mainurl']."\n".$cfg['subtitle'];
		if($cfg['charset'] != 'us-ascii')
		{
			$headers .= "Content-Type: text/plain; charset=".$cfg['charset']."\n";
			$headers .= "Content-Transfer-Encoding: 8bit\n";
			$subject = mb_encode_mimeheader($subject, $cfg['charset'], 'B', "\n");
		}
		if(ini_get('safe_mode'))
		{
			mail($fmail, $subject, $body, $headers);
		}
		else
		{
			mail($fmail, $subject, $body, $headers, $additional_parameters);
		}
		sed_stat_inc('totalmailsent');
		return(TRUE);
	}
}

AND this here is the header for aregular HTML email:

MIME-Version: 1.0
Content-type: text/html; charset=iso-8859-1

but remember corehacking is not the best way of achiving a goal! for my example you need to change the charset and type in the system/functions.php on line 3009.
