I need a script that will:
1) Remove duplicate email addresses.
2) Remove any email address where the mail-transfer-agent is has an invalid mx record.
3) Remove any email address containing invalid, inactive or parked domains.
4) Move to a separate list any email address containing a keyword from a list that I can update.
5) Remove any email address containing invalid syntax.
It must also remove any email address that doesn't exist on the server.

I have a script like that ready and tested on a list of 15 000 000 emails. The results are 94% valid (depends on email servers) and you'll get the result in a couple of hours.
