The primary service that we all need to de-google (or de-proton in this case) is email. The trouble is, the available email services all seem to limit you to 1 user and a few aliases, unless you want to pay a lot more. This kinda makes sense if you are using the proton domain name, they have name space limits and don’t want to become a spam source. However, if you bring your own domain name the breakdown of users and aliases is essentially irrelevant to the cost, and it should only be based on storage and transmit limits. I should be able to have as many user accounts and aliases as I like. This is what I get from MXRoute, and what makes it impossible for my to leave them even though they are mostly US based. I can’t find a solid replacement service that isn’t ripping us off with unnecessary limitations.
In case anyone suggests it, hosting your own email server is a very risky business, and best left to someone else.
They are close but I think mailbox.org charges per mailbox.
The best match I got was Migadu which I’m still tempted by but they’ve had reliability problems before.
The alternative is an smtp relay service in front of my own mail server, though not my preference.
