How mailbox assignment is protected

The main privacy risk in a service that reuses temporary addresses is accidentally exposing a previous user's incoming email. XFREE TEMP MAIL therefore does not treat a database row marked “free” as enough: the real inbox is checked before an address can be assigned.

Pre-assignment inbox verification

An available address is first reserved by the server, then authenticated and inspected. If messages are present, the service removes old mail and checks the inbox again. Only an inbox confirmed to be empty can move to the assigned state.

Quarantine after release

When a user releases a temporary email address, it is not immediately returned to the shared pool. Cleanup is followed by a quarantine period and another verification. Authentication, deletion or verification failures cause the problematic mailbox to be removed from the available pool.

Rate limits against abuse

The daily allowance of 25 addresses is combined with API request limits. Usage is associated with both a technical browser profile and the network, making a simple IP change less effective for bypassing the allowance while excessive request bursts are rejected before they overload the service.

What cannot be guaranteed

A reused email address can still receive a delayed message after cleanup if an external service sends it later. Temporary email should therefore never be treated as a confidential communication channel or used for critical accounts, personal documents or long-term account recovery.
