This would likely need to also be implemented in postscreen. :-( If
keyword-substitution is supported, apart from $pid, and $client_addr
also $rfc822_date would perhaps be useful to help search logs for the
right day.
With this, there is no need to separately log the helpful footer, the
information is already present in the receiving server logs, the footer
makes it more readily available to sender sites to aid in event correlation.
