If you are just using SMTP relay to verify /validate are can you get exempt and gain access to port 25? Or can you verify through secure SMTP on ports 587 etc?
I'm using a pay as you go account, and Im wanting to install either cobisi email verify for .net or Kellerman .net library.
Is this possible? I will use Reverse DNS, SPF, DKIM, DMARC etc, Im verifying legit email.
Any help would be awesome!
PS. I want to start my own email verification business like xerobounce.net or similar. If you are a freelancer please contact me as I need help understanding and setting up this business. Experts only please.
