Changing the password should not cause the email import from working. Please go back to the email import setup (Under Tools > More > Email) and confirm that it is still enabled and that you are sending it to the correct email address.
As I sent several of them without any context, I would have expect to find them (among other possibilities)in the "No context" category, bu they are not there. I search as well using the "search" option, but still nothing found. Trying to sent them by assiging a context within the email did not work either.
