Message contains NUL characters

[Denis Beauchemin]

Hello,

My postmaster reported the following error to me:
>Reporting-MTA: dns; email.usherbrooke.ca
>Received-From-MTA: DNS; smtpabc.usherb.ca
>Arrival-Date: Fri, 18 Apr 2003 19:58:02 -0400

Could this be caused by the following directives (mailscanner-4.14-9):
  Spam Actions = deliver forward spam at usherbrooke.ca
  High Scoring Spam Actions = deliver forward spam at usherbrooke.ca

If not, could MS strip those NULs from the emails?

Thanks!

Denis
