Sampsa, This end also has a gateway but it is restricted (at the moment). I have been experimenting with it mostly. Fred set it up for me on the Postfix side and I did the other end. That said, Multi-Watch makes use of CHIMPY:: to send out IP address changes. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of sampsa at mac.com Sent: Tuesday, January 29, 2013 23:09 To: hecnet at Update.UU.SE Subject: [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
