Hello all,
This to me appears to be an issue with my DNS settings, but I can't work this out either. I have an A record for lists.fiftyshadesof.green pointing at my server, and an MX record pointing at that:
lists.fiftyshadesof.green. 0 IN MX 0 lists.fiftyshadesof.green. lists.fiftyshadesof.green. 0 IN A 193.37.35.191
Why is the timeout on the names zero?
When looking them up they'll always come up as expired and invalid.
If you have static IP assignments I suggest setting the timeout to 86400 rather than zero. If you're on a system that changes up address more frequently, then 300 (five minutes) may be more appropriate.
