can you help...I want to set up a smtp server on a firewall which will then pass all mail onto an internal mail hub..pretty standard stuff...
I'm doing this in M$ NT and using exchange as the internal mail hub, but dont want to buy 2 expensive exchange servers, so i got hold of altavista mail server for the firewall. After looking at this altavista server I cant figure iut how I am supposed to tell it to forward all mail to the internal mail hub...on exchange there is an option to do this (i.e. forward all mail to another specified host)..do i need this option on the mail server, or can i use dns mx records.
Now I have looked at these, and what i make of them is that you can specify which hosts receive the mail and in what order of preference, just in case one goes down..etc. but I cant see a way that the MX records can be used to route deliver to the firewall smtp and then on to the internal mail hub..
any pointers much appreciated..
