What runs here
Outbound
Signed system mail
Form notifications, alerts, and account mail from side projects. No newsletters. No cold blasts.
Inbound
Mail comes in, too
MX for syshq.net points at this box, and inbound mail is accepted and delivered. Replying to something it sent? Go ahead. It gets through.
Hosting
Backups + side projects
A secondary host for side projects and the like, plus a backup target. Boring on purpose.
