Another small victory today.
A salesperson had almost convinced a client to move their email from 365 to Google because "they hold all the cards now". I stepped in and suggested they keep their email on servers that they control instead. The salesperson almost mocked me, treating me like a "nerd" who doesn't understand how the world works.
I was happy to be a nerd, if necessary, to explain the pros and cons of the solution to the client.
The result? The salesperson was politely thanked and "sent home", and I'm now evaluating some details of the new mail server, which, by the client's choice, will be based on OpenBSD.
Because people need explanations, not brochures.
Personally I would have gone with #Mailcow. Much easier to setup and administer. As much as I love #FreeBSD and #OpenBSD I sure as hell wouldn't recommend it for an SME.
Unless your goal is lock-in. Vendor lock-in. And in this case that vendor is you. Because let's face it, even in IT, OpenBSD is quite niche and FreeBSD is already niche enough.
