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.
Thank you Pete, that's strange. The TTL is set to 86400 seconds. That might have just been a peculiarity of dig when I ran it.
Good news everyone! I've got it working. It turns out my issue was with the mynetwork IP settings in my Postfix config. Things do now appear to be working. My only remaining issue is that the posts aren't appearing in the archive. Hmm.
