Verify a domain

After you add DNS records, SuperMail needs to confirm they’re live before it will route mail.

Running the check

Click Check DNS on the domain’s detail page (Settings → Domains → [domain]). We do a live lookup for every required record and return one of three states:

State	Meaning	What to do
🟢 Active	Record found and matches expected value.	Nothing.
🟡 Pending	Record not yet visible; waiting on propagation.	Wait 5-60 min, check again.
🔴 Missing / wrong	Record not found or value doesn’t match.	Fix at registrar, re-check.

Automatic polling

Once you’ve added records, SuperMail polls DNS automatically every 10 minutes for the next 24 hours. When every record turns green we flip the domain to Active and send you a notification email.

Partial activation

• Outbound activates as soon as _amazonses + DKIM are verified. This is usually within a few minutes.
• Inbound activates only when MX is also verified. On most registrars MX propagates more slowly than the CNAMEs.

You can start sending from the domain as soon as outbound is active, even if inbound is still pending.

Common failure modes

• “TXT mismatch” - you’ve pasted the value including the surrounding quotes. Some registrars add the quotes for you; double-quoting breaks the lookup.
• “DKIM not resolving” - Cloudflare proxy is on (orange cloud). Disable it for selector1._domainkey / selector2._domainkey / selector3._domainkey.
• “MX points somewhere else” - you still have the old provider’s MX record. DNS lets you have multiple MX records with different priorities, but SuperMail needs to be the primary (low priority number).
• “SPF too strict” - your existing SPF ends in -all (hard fail). Adding our include alongside that can still cause rejections on some receivers during propagation. Soften to ~all during cutover.

Removing a domain

Settings → Domains → [domain] → Remove. The DNS records in your registrar stay; you can delete them manually if you’re done with the domain. SuperMail stops accepting mail for it immediately.
