    I hosted my own mail server late 90s. It’s a drag but not the end of the world. You want it locked down. There’s many things that legitimately port scan but once the MX records went live port scanning went through the roof.

        Used to work at a big ISP, and before the days of Outlook 365, there were 5 engineers working flat out on running the staff email servers.

        Last time I heard from them, they got retrained and now look after the entire Microsoft 365 tenancy for the whole organization.
