🌐 Web query:

lektia.fr disposable email temporary mail provider classification

💡 Result:

**Classification: not identified as a disposable or temporary email provider.** The available evidence points to lektia.fr being a French educational-content website, and its published mail configuration lists an MX server at `mail.lektia.fr`. ([fr.all-url.info](https://fr.all-url.info/fr/lektia.fr/?utm_source=openai))

That’s not definitive proof of how its inboxes are operated, but I found no evidence that the domain offers temporary mail. **Treat it as a regular domain, not a confirmed disposable-email domain.** ([lektia.fr](https://lektia.fr/legal.html?utm_source=openai))

🌐 Web query:

site:lektia.fr Lektia official service AI educational content email contact disposable temporary inbox mailboxes

💡 Result:

Lektia’s site describes an AI tool for generating educational materials—courses, revision sheets, and exercises—and lists **contact.lektia@gmail.com** as its contact email. ([lektia.fr](https://lektia.fr/?utm_source=openai))

The available site information does **not** establish that Lektia offers disposable or temporary email inboxes; it describes temporary storage of generated PDFs, not mailboxes. ([lektia.fr](https://lektia.fr/legal.html?utm_source=openai))

Add lektia.fr to the local exceptions list unless an upstream source supports its disposable-mail classification.

Lektia’s public site describes an educational-content service and lists a Gmail contact, not a disposable-mail service. This exact entry can cause matching @lektia.fr addresses to receive the disposable verdict. The vendored upstream file is overwritten during refresh, so use the local exception list for this correction.
