This module caches URL tags in Redis for a configurable period of time. This could be used to reduce redundant or expensive processing.
See here for information on configuring redis.
For it to be enabled, the following should be set in /etc/rspamd/local.d/url_tags.conf:
enabled = true;
Currently, SURBL module adds a surbl tag containing symbols it added to the result and a redirect tag containing dereferenced redirects.
The following settings can be configured:
# Expiry time for a tag (default 1 hour)
expire = 1h;
# Prefix for redis keys (default "Ut.")
key_prefix = "Ut.";
# A list of tags not to persist (default empty)
ignore_tags = [];
