Normally done by attributing a value to the vertical-separator property
of the GtkTreeView widget, giving a similar effect (padding to each
row), by adding something along the lines of:

style "default" {
  GtkTreeView::vertical-separator = 6
}
class "GtkTreeView" style "default"

to ~/.gtkrc.mine (since contents of ~/.gtkrc-2.0 may be overwritten).

But in this case, Claws Mail doesn't seem to be affected. Other GTK+2.x
apps read the changes (Thunar, gtk-chtheme...), Claws Mail seems to
ignore it. Odd. It might be hardcoded.
