There are 2 limits to consider when managing Anti-Spam groups. The maximum number of groups per domain is limited to 20. The maximum number of users within these groups is limited to 150 across all groups, per domain.
The current limit is confirmed and cannot be increased by default. If you need to increase the limit, please raise a support case to be validated by Technical Support and our backend team can increase the limit. Only small limit increases are generally considered.
