Some time ago (2002/10/15) there were a discussion about spam to
inactive accounts.
I'm using MD 2.24 with sendmail 8.12.6 to protect my internal
M$-Exchange 5.5
When the message body contain the header "Precedence: bulk" and the
recipient doesn't exist, M$-Exchange doesn't send the NDR, so adding an
action_add_header("Precedence", "bulk") when the message is identified
as spam, may help a bit.
...
# of the spam score clamped to a maximum of 40.
# MUA filters can easily be written to trigger on a
# minimum number of asterisks...
if ($hits >= 20) {
return action_bounce("We don't accept SPAM");
}
action_change_header("Subject", "***SPAM*** $Subject ($score)");
action_change_header("X-Spam-Score", "$hits ($score) $names");
action_add_header("Precedence", "bulk");
# If you find the SA report useful, add it, I guess...
action_add_part($entity, "text/plain", "-suggest",
"$report\n",
"SpamAssassinReport.txt", "inline");
} else {
# Delete any existing X-Spam-Score header?
action_delete_header("X-Spam-Score");
}
...
