The server's Settings menu is nineteen groups, too many for the section
bar, so Settings was the one section left on the sidebar. The admin now
regroups the same 107 pages by job: Mail flow, Spam filter, Security,
Network, Mail & apps, Storage, Monitoring and System, with plainer labels
and protocol-level MTA pages in a dimmed Advanced group. View names and
URLs are unchanged, and a page the table doesn't know lands in
System › Other.
Settings › Overview is the new landing page: a card per category, the
guided setups, and the pages whose values differ from their defaults.
