It seems to me to be more complicated than this. I run my own MX server in house. THAT is my SMTP server. My upstream provider is who I connect my MX server to.   So what you are really looking for is an Internet Service Provider who will allow you to send that much mail through their servers. Most will not allow you to do that. Usually they will not have the reserve capacity to handle that load, so you will have to connect with one of the bigger upstream providers, the ones that your own ISP uses. MY ISP uses speakeasy in Seattle WA.

Well, things change quickly, they are now called Fusion Connect ( I have no clew as to how much they cost, or how you would connect to them. You need to use a local provider who will connect to your business.

My connection is provided my my local ISP and they provide me with a fiber optic connection to the internet. Since I have a static IP number, I have no modems between my self and the backbone. BUT, If I send out big globs of spam, they might not be happy and alter the terms of my service.

Presently, even though I have 5 servers and 30 workstations, they treat us as a residential customer since we also get our TV and Telephone circuits from them, and since thy are a Telephone Cooperative, and we were one of their first customers from back when our telephone number was "15".

Maybe not what you werre looking for, but you do have to connect your computer to something, and they will determine what you can do with it.
