[HECnet] Multinet SMTP mail delivery via gmail

Hello group I'm currently setting up Stephen Hoffman's NEWUSER new user registration system and as part of this I need to configure MULTINET to be able to send SMTP emails. I'd like to do that by using google mail as a forwarding service - does anyone have the necessary configuration information I'd require? I'd also like to be able to receive emails direct to the box, but this is a secondary requirement. I do have a linux server available running ubuntu that could act as a forwarding service if that's an easier setup. The plan, which is now coming to fruition, is to start a UK based public access Alpha and VAX cluster. It's getting close now! Cheers, Mark
