I want to set up a mail server that sends mail through a relay, e.g. smtp.google.com and receives mail via a domain registered at No-ip.com via email redirects. I know this is not the 'proper' way to set up a email server, but in this current situation, this is what I have to work with.
A pointer to a guide that shows what needs to be configured, and how, both on the postifx side and the no-ip side would be greatly appreciated. I currently run Ubunt server 8.04 LTS. Best regards, John
