[HECnet] Mail gateways?

Is anyone (aside from myself)* running a mail gateway between HECnet and the Internet at large? I remember there being a plan to set up a domain and then set up subdomains for each node, but not sure what happened to that.. * CHIMPY gateways mail to and from the Internet, rather awkwardly though and not all providers like the slightly wacky addresses it produces. To send, mail to: CHIMPY::smtp%"joe at example.com" Your inbound address is <NODENAME>::<USERNAME>@chimpymail.com Sampsa
