Undelivered Mail Returned to Sender

I'm getting a lot (like thousands) of Undelivered Mail Returned to Sender mails, how can I a) determine whether the spam mails actually came from my server and b) deal with all these return mails without having to sit here deleting them every few minutes.

Firstly, I'd like to be able to stop all this bounce mails coming in - there's been around 20k in the last couple of hours. Once that is under control, I'd like to determine if the mails actually came from my server or whether the email/return address was just spoofed.
What can I do? Its a debian server running postfix
