Stale or throttled
Check too rarely and mail is late; too often and the provider slows you down.
Flaxxa Mails keeps each connected mailbox in sync by checking it on an adaptive schedule. A mailbox with recent mail is checked about every minute; a quiet one backs off to about every 30 minutes. New messages are threaded as they arrive and appear live in the open inbox.
