Hi, http://mxtreme.com/products/mxtreme The Borderware MXtreme Firewall is a Mail proxy against SPAM. Every user has a SPAM-Folder on the Proxy and is able to log in. The mailbox-GUI seems to be IMP (the URLs are like /borderpost/imp/message.php3?index=7&array_index=6) Do you know if they provide the source code, too? Philipp
