Using the default theme (haven't tried others), when I click on a message in the list, a preview is shown and the row turns grey showing it's read. A small purple indicator at the far left od the row indicates the active row. The challenge is that when deleting the message using the buttons on the right end of the row, it's not easy to tell if you are deleting the currently selected message. The entire row should have some sort of highlight, like an outline or different background colour, or the currently selected indicator should be at both ends of the row. My preference would be a different coloured box around the row.
