I am intrigued by the source and chronology of the "two line sendmail
rule" suggestion. If the source was the Home Office people as you suggest
above then they were surprisingly well briefed about the capabilities of a
completely new facility in sendmail released only a few months previously.

The sendmail 8.10.x distributions include a sample filter that when
compiled and configured logs every incoming mail message so at least this
application was well flagged! However the full utility of the filter's
implementation is not so obvious.

The main use (and purpose?) of the sendmail filter (AKA "milter") facility
so far has been to detect and reject messages containing executable
scripts within MIME attachments.
