Implement static queue policy (replace CurrentConnections)

To replace the deprecated function CurrentConnections(), the following example can be used. Note that the specific configuration depends on, and should reflect, the present pre-delivery scripting.

Create a static queue policy by using the new options in the Web Admin menu, as follows.

First, configure a counter that will be valid for all recipient domain and all transportid - in this example using the concurrency value "15".

1. Go to Configuration -> Queue -> Pickup Policies.
2. Click on + Add to create a policy of the type counter.
3. Select the fields recipientdomain and transportid (multi-select list).
4. In the field concurrency, enter the value "15" (use the present script value).
5. Click on Add.

Then, configure a separate condition for each specific recipient domain that should use another concurrency value and a specific transportid - in this example only one - "10" for "google.com" and "outbound":

1. Click on + Add to create a policy of the type condition.
2. Select the counter "transportid, recipientdomain".
3. In the field transportid, enter the value "outbound" (use the present script value).
4. In the field recipientdomain, enter the value "google.com" (use the present script value).
5. In the field concurrency, enter the value "10" (use the present script value).
6. Click on Add.

Following the example, the static queue policy should now look like the following figure.

Thoroughly compare the new static queue policy with the deprecated pre-delivery scripting, and verify that the policy achieves the desired result, and then finish by cautiously removing the script.

Note that the options rate and grouping can be used, too.
