+    Even if we haven't reached the retry time in the hints, there is one more
+    check to do, which is for the ultimate address timeout. We only do this
+    check if there is an address retry record and there is not a domain retry
+    record; this implies that previous attempts to handle the address had the
+    retry_use_local_parts option turned on. We use this as an approximation
+    for the destination being like a local delivery, for example delivery over
+    LMTP to an IMAP message store. In this situation users are liable to bump
+    into their quota and thereby have intermittently successful deliveries,
+    which keep the retry record fresh, which can lead to us perpetually
