If you need to disable some receivers to get messages you can create a blacklist file. During installation an example file will be copied: /etc/smsd.black.
This is a simple text file that contains the phone numbers of the receivers that you want to disable. You can add comments that start with an # character.
Example:
491721234567 # Stefan Frings
491721111111 # Test
If you need to enable only a specified list of receivers you can create a whitelist file. Normally you do not have a whitelist - everybody can receive SM except those who are in the blacklist. If a recipient phone number is in both files it will not get a SM. During installation an example file will be copied: /etc/smsd.white.
This is a simple text file that contains the phone numbers of the receivers that you want to enable. You can add comments that start with an # character.
Example:
491721234567 # Stefan Frings
491721111111 # Test
Note: You can edit theses files without restarting the porgram.
