We are located at Innopolis (Russia). Altogether, our team speaks French, Russian, English and German.
Warning: we are currently mass-scanning the public network against port 25/tcp and eventually checking if STARTTLS is enforced or not. If you've seen us in your firewall or SMTP logs, do not be afraid. We are not attempting anything invasive. We are simply checking today's

statistics on worldwide SMTP health.
