I'm handling an Exchange 2003 mail server. The info@mycompany.com has been used by someone as return email address. But since a lot of spammed email addresses were invalid, those spammed email server are sending back tons of non delivery emails and messages back to info@mycompany.com , how can I resolve this?

It's been 2 days now, and about 3 messages a minute, what can I do?

Thank you.

The short answer is that you don't; you suck it up. It's one of those side effects that has happened because of spam filters not being ready for the attacks and allowing messages in to be NDR'd back.
There are some things you can do. Get your spam filter to scan and drag out the key words of the NDRs so that you get far fewer arriving in the inbox.
Things will calm down.
