My plan would be to use what mailinglists do: send mails with a varying
envelope-from address which has the subscriber's email-address in it.
The return-path of your outgoing email could be something like:
Return-path: <mailingid-reciplocalpart-recipdomain-bounces@???>
If the message to reciplocalpart@recipdomain bounces, the return message
will be sent to the Return-path which you can filter out any way you
like.
For example by delivering them to a special mailbox or piping them to a
script which extracts the original recipient from the return-path the
bounce was sent to and automatically removes the entry from your DB.
Extracting exactly -why- the message bounced could be a tough task.
Lots of MTAs which all use their own DSN-messageformat make this
practically impossible.
HTH,
