Documentation

Rate Limiting

To implement hour-based Rate Limiting, the software keeps a cache file for the current hour in the cache directory. For every message sent, one byte is appended to this file.

When the file size becomes larger than the $config['ratelimit'] configuration option, no messages can be sent until the next hour.
