We have a client who has an Exchange server on the end of two xDSL lines. We currently deliver via SMTP to the IP address of one of the lines. We would like to have postfix try the other line if the xDSL on the first one is down.
Looking at the docs fallback_rely would seem to do the trick. Do I put in the transport map: clientsdomain.co.uk smtp:[xxx.xxx.xxx.xxx] clientsdomain.co.uk relay:[yyy.yyy.yyy.yyy] where x is the main line and y is the fallback line?
