How We Verify Orange, Wanadoo, Free.fr, SFR & LaPoste (France) Addresses
High Bounce Rates on Legacy @wanadoo.fr, @neuf.fr & @club-internet.fr
Millions of French consumers still use historic @wanadoo.fr (now Orange) and @neuf.fr (now SFR) addresses. Under French telecom rules, canceled fiber/mobile accounts have their email addresses deleted after 6 months—creating massive hard bounce spikes.
Avoiding Vade Secure & Signal Spam Honeypots on Orange & LaPoste
Orange, SFR, and LaPoste.net use Vade Secure filtering and feed Signal Spam trap data. Cleaning dead @orange.fr and @laposte.net contacts before mailing prevents instant IP blocklisting (`OFR004_102`).
Respecting Proxad / Free.fr Connection Limits (`mx1.free.fr`)
Free.fr (`mx1.free.fr`) blocks senders who open aggressive parallel SMTP sockets. KaijuVerifier throttles concurrency per French ISP automatically.

Frequently Asked Questions — Orange, Free.fr & LaPoste Verification
Do @wanadoo.fr email addresses still work in France?
Many historic @wanadoo.fr addresses still route to `smtp-in.orange.fr`, but Orange regularly purges inactive @wanadoo.fr accounts and converts abandoned ones into spam traps. Always verify @wanadoo.fr addresses before sending.
Why did Orange.fr block my server with error OFR004_102 or 421 Trop de connexions?
Orange uses Vade Secure to monitor hard bounce ratios and Signal Spam complaints. If more than 2% of your @orange.fr / @wanadoo.fr recipients bounce with 550 5.1.1, Orange throttles or blocks your sending IP.
