First I'd check if Preserve deleted messages until Pegasus Mail closes is set. If so, secondly I'd verify the integrity of your Deleted Messages folder in case you have chosen 'Deleted messages' folder persists between sessions. Right-click on it and pick Check consistency. If anything wrong is found act accordingly. Option in Bold are found in Basic settings and Advanced settings of Pegasus Mail General settings.
