Recording relayed messages and headers

[Charles Leeds]

My company wants to monitor all incoming and outgoing messages that are
relayed through the qmail relay.  The qmail box forwards all mail for our
domain to an internal mailserver using smtproutes, and has no local users.

Is there any way to record all messages (and headers) of incoming and
outgoing messages that are relayed by qmail?

Thanks,
