@kyle I assume this was supposed to be a reply to my earlier post. Anyway, that's not really what I'm going for. There are several addresses that I trust completely. I'd love to automatically forward any Email from these specific addresses. I mean I know in theory a spammer could spoof one of those addresses, but spammers aren't likely to get hold of that address, and even if they did, they'd still have to hit upon one of the few magical trusted addresses.
@kyle Yeah I'm just using .forward in the home directory of the secret forwarder account I manually forward to. What I'm looking for to use in this and a few other situations is what you might call a smart .forward replacement that can actually look at factors such as who the Email is coming from, etc. and decide whether to forward it or not.
