Globally it makes me a bit nervous to be doing destructive operations on
${MAIL_DIR}, but that isn't specific to this patch. I wonder if it would
be worth globally replacing the variable with something like
TEST_MAIL_DIR just to make collision with user environment less
likely. Or maybe it's enough just to be careful to override MAIL_DIR.
