One of the reasons for using existing verify map with "invalid" values was that those counters will be purged every 12h. Sure, if you restart a lot, limit still can be exceeded. > - The problem with per-domain in-memory counters is that they can > use up a lot of memory especially with sender domains. Worst case memory usage is doubled: one value for recipient (as now) and one for domain (new). Our system shows 0.4% increase.
