[Exim] not receiving bounce messages with exim

I recently installed exim in place of qmail and am quite happy with how it works. It is very simple to configure, yet has some great spam filtering capabilities and has a very low overhead.

I am having one problem though. I am unable to receive any bounced messages. It appears to send the bounce to nobody@??? just fine. I have nobody configured in the alias file. I can send mail to nobody directly and receive it with no problems so I think the email address is set correctly.

I was wondering if anyone had any ideas as to what I was doing wrong or could point me to some documentation that may help.

below is an excerpt of the log file (domain names have been changed for obvious reasons).

Thanks,
