DYNAMICSCREENUPD.SEM minutes to block

Hi,

For a long time I've used the Content Filter to create a DYNAMICSCREENUPD.SEM file in the App folder so MDaemon will block an IP address for a number of minutes if it has sent spam.
The format I use is:-
IP address(space)number of minutes
For example:-
1.2.3.4 30
In the latest version of MDaemon I have noticed that this still works but the number of minutes to block is ignored. The actual number of minutes looks to be set by the values entered in the Auth Failure Tracking tab of the Dynamic Screening window where I have set all 4 values to 20 minutes.
My questions are:-
Is there a way to specify the number of minutes to block in the SEM file?
While mostly the IP addresses are blocked for 20 minutes there are some that show for longer, perhaps double, it's a bit hard to work out exactly. I've attached a screenshot of the dynamic blacklist which was taken at 10:15
Some of the values still have more than 20 minutes left. The IP addresses have a 20 at the end which came from the SEM file.

The functionality of the dynamicscreenupd.sem file was changed when we updated the Dynamic Screening system. 

You can still put a list of IP addresses in the sem file, but the time parameter is ignored now.   Each IP will be blocked for the default amount of time, which is configured under Security / Dynamic Screening / Auth Failure Tracking. 

We will look into improving the sem file functionality for a future version.
