Number of Whitelist or Blacklist Entries Allowed

The limit for whitelists and blacklists  are based on physical limitations, not on license or software limitations.  They are a combined limit based on an aggregate across all users on any single SpammerTrap. 

Example: 1,000 Users, each with 10 email addresses in their whitelist and 10 email addresses in their blacklist will be a combined total of 20,000 entries in the site whitelist/blacklist table. 

SME-500 and SMB-250 models have a total table size limit of 32,767 entries.

SME-1000, and all GEM models have a total table size limit of 2,147,483,647 entries.
