- Cards and charts link to the page they're about: pending messages to the queue, bans to blocked IPs, report warnings to the reports, and so on, shown only to viewers who may open that page. - A one-line status under the greeting: what needs a look (failed tasks, messages retrying, recipients given up on) or, when nothing does, what's there. Each phrase is a link. - Counts from the server's own objects stand in for live metrics it can't report, and a live number with no source reads as unknown, not zero. - Who uses the space: a treemap of people sized by storage, colored by how near their quota they are, each tile opening the account. - Where mail is waiting: queued recipients by destination, split into waiting, retrying and given up, each row opening the filtered queue. - The weekly rhythm: messages by hour and weekday, shown once metric history exists. - Dashboard tabs are titled by their label.
