You could script this fairly easily:
- build a text file with one email per line,
- parse through the file with a for loop to look up each address 
- use the "list_members" command to find if an address is subscribed
- unsubscribe them to the list
- run the script daily or hourly.

You could also build this into the add_user functionality of the web and
email cgi's; have them check the text file for a negative hit before
allowing the user to be added. It would take all of about three lines of
code in each program.

Open Source is the best!
