domain mailboxes: a field note from a restaurant
28 Oct 2025
How a restaurant deals with domain mailboxes — and what usually goes wrong.
The problem: a tag manager container with leftover pixels. The domain mailboxes check fails for a restaurant.
The job started when a restaurant realised their domain mailboxes had been wrong for months. Nobody noticed because the site still loaded.
domain mailboxes for a restaurant is nothing like domain mailboxes for a multinational. The scale is tiny but the stakes are the same: one wrong record and nobody can reach you.
We deployed a fix for domain mailboxes at 5 PM on a Friday. It worked, but if it had not, we would have had no one available. We no longer push to production after Thursday noon.
Email deliverability is nobody’s favourite topic, but a restaurant lost two bookings because domain mailboxes was misconfigured and replies landed in spam for a week.
Complexity is the enemy of uptime. a restaurant had three layers of proxy in front of a site that gets two hundred visits a day. We replaced it with a static page and correct domain mailboxes.
DNS propagation is not instant, but it is not magic either. We explained to a restaurant that the TTL on the old domain mailboxes record was 86 400 seconds — twenty-four hours.
