Or use no secondary MX and have faith in the fact most email servers are set
to try again for 4 days? :)
At least Telstra does one thing right here. Click a web page and add your
domain - done - working secondary MX for you (If you are a direct - ISDN -
STATIC ADSL - FRAME RELAY customer that is).
However ERTN ain't working with them? Mail comes through eventually - we
are 24/7 connected. However in the times we have been offline for 3 days
for upgrades, I tried a ERTN to speed things up and nada. So is this RFC
for an addition to a 'standard' not implemented by everyone? Sort of a
Microsoft way of applying standards?
