Where would you expect bounces to go?

If you don't have good logs, or even easy to read logs, then you are in for a long debugging. You also need to have a firm understanding of what your applications are doing. Are they using /usr/lib/sendmail? Are they speaking SMTP with a particular mail server? What do the logs say? If you don't have good logs, the next best thing is tcpdump or some other sniffer that can watch SMTP traffic. Capture a message off the wire with tcpdump and then use tcptrace to reconstruct it (or ethereal).
