Spam Filters

All enterprise spam filtering and attachment blocking rules are enforced for messages sent to any list hosted by ITS. For more information on spam control at NIU, see CanIt-Pro spam mitigation.

Because enterprise spam scanning is already in place for all list traffic, ITS does not recommend or support the use of  the internal spam controls.
