The ASN module retrieves ASN numbers and related information such as the country code of the ASN owner and the IP’s announced subnet. These details are then made available to other plugins as mempool variables.
The module exports asn, country and ipnet1 as mempool variables available from Lua after prefilters stage.
The ASN module is enabled by default and its settings can be found in /etc/rspamd/local.d/asn.conf.
# Provider: just "rspamd" for now
provider_type = "rspamd";
# Provider-specific configuration
provider_info {
ip4 = "asn.rspamd.com";
ip6 = "asn6.rspamd.com";
}
# If defined, insert symbol with lookup results
symbol = "ASN";
