Hi,
We have just signed up to a mail filtering service so now I want to put a filter into BM that will only accept incoming emails from a particular network range (203.84.134.0 to 203.84.135.255) but when I try to setup a filter Public to Private with a source network of 203.84.143.0 subnet 255.255.254 it will not accept this. I assume that the source address that BM is expecting is one of the public addresses on the BM server.
How can I create this filter?

thanks

Keith
