|Situation||Trying to add a list of addresses to a filter and it will not save. Is there a character limit?|
|Solution||Creating/Editing a filter has a character limit of 5000 characters.|
When creating or editing a filter and it does not save, this is probably due to the character limit.
Filters have a limit of 5000 characters
If you are adding a list of addresses or CIDR ranges to a filter, it would be best to use the Sender Lists. These do not have a character limit.
This can be found under Security Settings > Email > Sender Lists.
