Mail capacity

Plan mailbox growth before quotas become an emergency.

Model current mailbox footprint, annual growth, primary headroom and additional backup copies for a mail platform or migration.

What it answers

Use the result to make the next technical decision.

Size primary and backup storage for a mailbox population while making long-term growth and headroom explicit instead of assuming today’s used space is enough.

Limits

Read observations in context.

Mailbox distributions are rarely uniform, deleted-item retention varies, indexes consume space and backup compression/dedupe differs by system. Use real mailbox statistics when available.

Privacy

Marketing analytics never receive the target.

DotMoose records only the tool name and a coarse success/error outcome for marketing analytics. Active server diagnostics use bounded operational security logs without placing the entered domain, IP, URL, DNS answer or report contents into marketing telemetry.
