I've got many spam emails sent from non existing senders to unkown users and
do not want to generate bounce messages.
All files in sendmail queue was removed on Friday and now (Tuesday) I have
800+ bounce messages in the queue. Plus, why do I have 9000+ files in the
sendmail queue now?
I hope Mimedefang can help reducing the problem but I am new to it.
Have I missed anything here? The manual smtp tests indicates that it can
validate recipient users, but many bounce messages still got created (by
localhost (localhost)) and stuck in the queue.
Please advise! Thank You (:
Below you'll find my filter code and the manual smtp session output and one
of the bounce message headers (note that I replaced the actual server with
mimedefang_server and similarly for [EMAIL PROTECTED])
sub filter_recipient
{
my($recip, $sender, $ip, $host, $first, $helo, $rcpt_mailer,
$rcpt_host, $rcpt_addr) = @_;
my $relay = undef;
$relay = "internal_server" if ($recip =~ m/[EMAIL PROTECTED]/i);
if ($relay)
{
return md_check_against_smtp_server($sender, $recip,
"mimedefang_server", $relay);
}
return('CONTINUE', "OK"); # accept recipient if dont find relay
}
