DSN: Failed messages

[Jon12345]

I get loads of messages like this:

- DSN: failed (Happy Birthday from My Forums)

- Delivery Status Notification Failure)

Is this normal or do I need to update a setting somewhere?

Thanks,

Jon

Example for the Happy Birthday one was...

This is a Delivery Status Notification (DSN).

I was unable to deliver your message to
[email protected].

The error was;
Domain "theirsite.net" can't receive email

It seems like the Happy Birthday thing couldn't be sent? If so, how do you guys have this kind of thing setup?
