quota-status works absolutely fine, our frontend MXes defer mails for
mailboxes over quota. But when we try to send a mail to the mailbox
nevertheless through LMTP (i.e. because it was generated on a server
that doesn't check quota-status), it is deferred in LMTP in the
END-OF-DATA phase, not in RCPT TO as expected.
