Ok, so miss read the question a bit... (Was thinking the bridge was the mail server too - used to my own hardware shortage :) But still, I think you'll get it working by swapping 'me' with the ip of your mail server. Can also use subnet to allow your own net unlimited access. > There isnt much you can really do as to shape incomming traffic, however > you can limit how fast you accept the incomming data.
