Edit: or at least move them to another usergroup..

Bounced emails usually do mean something, although it may not necessarily mean the address is invalid. What EZBounce does is:

1. allows you to inspect the reason the email was returned before taking action, so if no action is necessary (e.g., mailbox full) you do nothing

2. places a link in the bounced email that when clicked can move the user into a special user group (I set up one called "Inactive"), which is what you requested - then if you wish you can periodically prune members of that group

3. sets "Receive emails from Admins" to "off" so that you can at least exclude that group from mailings of newsletters, etc.
