  4. Set the value of hidden key "throttling_sender_enabled" to yes. Otherwise, the Sender-based throttling feature will take effect on all senders.

    insert into tb_global_setting (section, name, value, inifile) values ('smtp_traffic_throttling', 'throttling_sender_enabled', 'yes', 'imss.ini');

  5. Set the value of hidden key "throttling_sender_list" to your custom values, which can be separated using a semicolon (;). Below is an example with "*@test.com" or "test02@test1.com" as specific senders.

    insert into tb_global_setting (section, name, value, inifile) values ('smtp_traffic_throttling', 'throttling_sender_list', '*@test.com;test02@test1.com', 'imss.ini');

  6. Restart S99MANAGER and S99SMTPCONNAGENT using the commands below:

    /opt/trend/imss/script/S99MANAGER restart
    /opt/trend/imss/script/S99SMTPCONNAGENT restart
