Could you build this?
Partial A UI and syntax or MX-record checks are easy to vibe-code, but reliably confirming that a specific GMX mailbox exists needs provider-side data or SMTP probing that providers block. Accuracy is the hard part.
What it would actually take: The basic checker needs DNS MX lookups, syntax validation, and a job queue. Mailbox-existence verification would require SMTP probing with rate limiting, rotating infrastructure, and handling of anti-abuse blocks. Accurate results would depend on access to provider data that a solo builder does not have, and the tool is easy to misuse.
