Secure Email Delivery Licensing
Register, obtain your API key, and authorize your VPS IP address — then let our mailer app send with confidence. Every send is validated against your Tunbis mailer account before a single message leaves.
$ python mailer.py start
Authorization successful from IP: 203.0.113.45
✓ SMTP smtp.gmx.de OK
[1/500] Sent OK -> user1@example.com
[2/500] Sent OK -> user2@example.com
...How It Works
1. Register & Get API Key
Create your account and instantly receive a unique API key to place inside your config.json.
2. Authorize Your VPS IP
From your dashboard, add the IP address of the VPS that runs our mailer app. Only authorized IPs can send.
3. Send With Confidence
Every time mailer.py runs, it checks with mailer.tunbis.com to confirm your key & IP are valid before sending.

If the API key or IP doesn't match, the mailer stops and reports "Unauthorised." — no email is sent.
