msg:routing_domain
Name
msg:routing_domain — Set or return the routing domain for a message
Synopsis
msg:routing_domain(...);
Description
Set or return the routing domain for a message. To return the routing domain, use this function with no parameter. Ensure that you return the routing domain in lower case.
In order to set the routing domain you must add the following to your code: require('msys.extended.message_routing');. This will register a hook that will allow the routing domain to be set from Lua.
-- DB query to find SMS destination. Query returns "domain"
require('msys.datasource');
require('msys.db');
local orig_domain = msg:routing_domain();
local ritr, dberr = msys.db.query("ecdb", "SELECT to_address FROM smpp.sms_address_mapping
WHERE from_address = ?", {orig_domain});
Warning
In some circumstances, using this function or simply requiring it in your policy can cause performance issues, such as causing Momentum to become unresponsive and restart or causing additional overhead per message. To alleviate this, set keep_message_dicts_in_memory to true.
The data cache used in the preceding example must be defined in your configuration file. For more information, see “ds_core - Datasource Query Core”.
Enable this function with the statement require('msys.extended.message_routing');.
Warning
In the validate_data_spool_each_rcpt phase you can take action on each message, after possible alias expansion. Actions taken in this phase are scoped to an individual recipient.
In the validate_rcptto phase you can validate that a provided recipient string is valid. Actions taken in this phase affect the current batch.
