My Gmail has been on vacation mode for almost two years. The auto-reply message,

"Your email was undeliverable as the user no longer monitors the Inbox.
The email address is deprecated. A hard bounce forthcoming.
It should be removed from all mailing lists, contacts, address books,
records, etc.
You may contact the user at mozychan@##########"

I STILL get email there.

When is enough? Hard bounce when?
