Submit a domain or subdomain you control. Then point its MX to the shared inbound mail host before sending it for review.
Set DNS like this:
A:
Host: mail
•
IPv4 address: your-server-ip
MX:
Host: @
•
Mail server: mail.yourdomain.com
•
Priority: 10
- For yourdomain.com, point MX host = @ to the shared inbound host mail.yourdomain.com.
- If you want a dedicated host like mail.yourdomain.com, create its DNS record first, then point the domain MX to that host.
- If you use Cloudflare, keep the mail host as DNS only, not proxied.
