You see, there's too much normalization of the idea that everyone should be free to do everything. We see too much push to have developers maintain their own infrastructure, which is partly why there's such a big (and artificial) push to put everything in the cloud, and this often ends up costing much more in the long run. Just like how regular developers shouldn't be able to push work in to a cloud that'll end up costing tens or hundreds of thousands of dollars without deliberate, thought out reasoning, random people in a company should not be able to set up outgoing email using a company's domain without good reasoning. If a person or a group were responsible for outgoing email, then nobody would be allowed, nor should they be able, to send without going through that person / group. Problem solved! But if you think it's OK for any random person at an organization to just set up whatever kind of outgoing email they want, well, you get what you expect.
