:)) no seegar! Imail will receive on RFC1918 ip and then resolve the @recipientdomain via DNS. >Couldn't users on that domain send to and receive from users behind >the router only? no. they send "to: anybody@anywhere" and "from: whatever@wherever" and Imail will find find and deliver to @anywhere. Once a sender is "authenticated" by Imail, the sender can send as whatever@wherever and IMail won't filter it.
