I searched and found a tidbit of info in a post from 2005 but did not really answer my question I have. I just set up a client with Postini and asked the client to add the packet filter of 'network' 'mask' Though through testing from Postini the Firewall test failed

"Testing firewall from to xxx.xxx.xxx.115... failed (accepted connection)".

Our server with a router gets

"Testing firewall from status:passed (did not accept connection)".

They are still getting SPAM. I do not have remote access so all the help I get will be delayed for my response. Thanks alot.
