The problem is most probably about the Free Space in your drive where your smail queue ie present.

Here is what you should do ;

Find \bin directory and you will see EdgeTransport.exe.config file in that directory.

Open the file by using Notepad ;

Change the two lines below;

add key="QueueDatabasePath" value = "d:\newlocation" //you can choose another drive name that present in your Server.

add key="QueueDatabaseLoggingPath" value = "d:\another-newlocation"
