• Security: Numerous improvements to security and robustness,
    including: Every 15 minutes a script now tests web login, sending,
    receiving, IMAP, disk space, and mail queue and pages 2 FastMail
    engineers if any check fails or displays unexpected results; Rate of
    received and sent messages per user are tracked and potential spam
    problems cause relevent accounts to be disabled and FastMail staff
    notified; Signups tracked--potential abuse by signing up too many
    accounts for one person now tracked and dealt with; quotas added of
    100MB per user--anyone using over 50% of quota is notified
    automatically. These changes should lead to improved service through
    avoiding abuse of the system.
