Why isn't my K-9 Mail receiving emails from a pop account since the last update on Friday September 26?

AC Question

K-9 Mail is not receiving emails from a pop account since the last update on Friday September 26.

My hotmail account is working but our corporate account will not receive emails since this update overnight on Friday Sept 28. It appears to be a change to the security for the pop server. The option for security setting of "None" is not an option. It is set to "Password, transmitted insecurely".
