how to fight fake email addresss?

[Martin Hepworth]

Hi

never trust the 'from' address, use ip-addresses use with the rules.

I have an s separate email gateway machine.

I set mine so email from the server (or LAN) ip-address gets virus
checked, NOT spam checked but a standard signature attached.
