SYMPTOMS
When there are already a lot of existing domains, adding new domains may take a long time. For example, if there are approximately 6,000 domains in the metabase, adding another domain takes about two minutes. The time needed for successive entries is even longer.

When you add a domain, Smtpsvc cannot route any e-mail messages (blocked on the metabase lookup). This problem occurs in the code where the metabase rebuilds the hash table after a new key is added.



CAUSE
The delay that occurs when you add a new domain is attributed to the time it takes to enumerate a large number of domains.
