Mailbox quota management

Mailbox usage and quota sit side by side for every domain, sorted by how full they are. Filters find the mailboxes about to fill up, the heavy senders and the ones nobody has opened in a long time. Raise a quota before mail starts bouncing; the panel won’t let you set one below what is already used.

What it does.

When a mailbox fills up, incoming mail bounces, and the customer is usually the one who tells you. Sort by fill percentage and raise the quota before that happens. Heavy senders are flagged in the same list and read against the sending limits, so you can tell whether one mailbox or the whole domain is hitting the ceiling. The mailbox count comes from the same data as the account list, so the two never disagree.

  1. Usage and quota side by side for each mailbox, sortable by how full it is.

  2. Filters for full mailboxes, heavy senders and mailboxes unused for a long time.

  3. The domain picker is shared across the email screens, so going from the mail queue to the mailboxes keeps you on the same customer.

  4. Quota changes go through the panel’s own API, so the customer sees the same limit in webmail.

  5. A quota can’t be set below current usage. The panel would refuse it, so the form refuses first.

  6. Mailbox counts come from the account profile, the same data as the accounts list.

  7. Heavy-sending mailboxes are read alongside the limits on the sending policy screen.
