At what level do ISPs control ports? (beehaw.org)

I'm aware most ISPs do not allow for port 25 to be open for email use outside of business licenses, but at what level is that controlled? Can I get around that by owning my own router? Owning my own modem or ONT? Or is this just a thing they mystically control further up the pipeline that a relative layman such as myself can't get around?

For a small business, a service such as GoogleApps or Microsoft365 is likely going to be a cheaper solution than self hosting this. Plus including productivity applications and cloud storage as part of the package in most instances.

It will be much, much safer as well. If you're unsure of how to do this, do not do it yourself. Setup a home lab, sure. Use it to learn but do not run your business this way!

Is there a service that is only email? Most of the offerings in those packages are either too much bloat of applications that are unnecessary, and/or are too expensive for what they actually would provide that we would use.

I'd much rather keep using the tools that we're used to and have set up than move to a different ecosystem, especially one that tracks a lot of the data we use with it

https://proton.me/mail has not unreasonable pricing for just mail.

Ooh! That looks doable!

Microsoft’s Exchange Online Plan 1 is email-only and is 4/month per user. There are probably cheaper IMAP providers, but EO1 is full exchange: mail, global address book, calendars, etc.
