Mail Delivery Checklist
Check MX, IPs, PTR and basic email auth for outbound mail.
The tool:
- Fetches MX records for your domain
- Resolves those MX hosts to IP addresses
- Performs PTR lookups for the IPs
- Shows SPF/DMARC/CAA via the Email Auth logic
This helps you quickly see if your domain is set up in a way that mail providers typically expect.
