Here is the solution about how to secure members email address.
1. Open userinfo.php in root directory
2. search for this line
$xoopsTpl->assign('user_email', $thisUser->getVar('email', 'E'));
Replace it with these two lines
$false_mail = preg_replace("/@.+$/","@somemail.com", $thisUser->getVar('email','E'));
$xoopsTpl->assign('user_email', $false_mail);
