It's a well-known technique.  You create a shellscript something like:

  #!/bin/sh
  exec ${RECORDIO} /var/qmail/bin/qmail-smtpd

Call it "qmail-smtpd-wrapper.sh".  Then in your /service/smtpd/run script, you
invoke that wrapper instead of qmail-smtpd directly.

When RECORDIO isn't explicitly set (by the tcpserver rules database, etc),
that variable expands to nothing and qmail-smtpd is invoked.  But you can do:

  1.2.3.4:allow,RECORDIO="/path/to/recordio"

... in your rules database to capture SMTP traffic from 1.2.3.4.
