Postfix mailbox size limits are not a quota mechanism. They merely make explicit that all resources must have sane limits. To support quotas with Postfix, you need UNIX filesystem quotas. Use Dovecot if you need a mailbox store with per-user filters, per-maildir quotas, and so on. Recent Dovecot versions should support LMTP, so performance is not an issue. Wietse
