The address is valid, but account owner has not logged in to the account for
an extended period of time. The domain apparently has policies and procedures
which result in the rejection of messages addressed to accounts which have
been inactive for an extended period of time.

At the very least, you should set the subscriber to NOMAIL, so that your
list and the server on which it is hosted do not get tagged as spam sources
due to your continued attempts to deliver email to a non-deliverable address.
If I received a delivery error message of this nature, I would delete the
subscriber from the list.
