Thanks to both responders.I understand now what the problems was. I
will look into redirecting using aliases but on my test rig I used the
following to get this working.
if ($Subject =~ /\brun ls \b/i) {
$cmd = "ls";
$tmp = `$cmd`;
}
Pete.

The problem is that your filter *must not* print anything ...
Definently not good. Look into sending the mail to a program instead
(cf. sendmail's aliases database - entries starting with "|").
If using the aliases database, you may want to end the command with
an "||exit 0" just in case it fails - so a DSN isn't sent back to the
sender (unless you want errors to be reported). There are some cases
(e.g. spamtraps feeding "|spamassassin -k") that shouldn't DNS back
on
errors.
