Catch-all mail for GSA SER, RankerX and XRumer
Sites send a confirmation message when you register. Your tool needs addresses that receive it, on a domain whose reputation belongs to you.
What people use today
| Approach | What it costs you |
|---|---|
| A domain plus Zoho or cPanel, set up by hand | An hour per domain, DNS records typed by hand, and it breaks silently |
| A ready catch-all on somebody else's domain | About the same money, but the domain is shared: other people's registrations burn its reputation |
| Desktop software with hosting | Around $99 plus $9 a month, Windows only, tied to one machine |
What we do instead
- The domain stays yours. Reputation belongs to whoever burns it.
- Setup takes a minute: paste a Cloudflare bootstrap token and the MX record is written for you.
- Credentials come in the form GSA SER expects, and export as a list.
- One record on your zone, the MX of the subdomain. The rest of your DNS is untouched.
- The management API does the same things the panel does, so a script can add and release domains without a browser.
Many threads, one mailbox
GSA SER opens many POP3 connections at once. Without serialization two threads see the same message, both take the code, and one deletes it from under the other. Each mailbox here takes one POP3 session at a time and tells the rest to retry.
The address does not announce itself
The default subdomain label is neutral and random, never otp. The receiving hosts live on a separate mail domain, so the name in the Received header does not point at a page selling catch-all mail.
