We are running exchange 5.5 in open relay mode, because our mac computers can not send mail if the sever is set to secure password authentication. The pcs do fine but not the macs which account for half of the systems on our network.
We are suffering with relays from outside, have had several crashes by the overload of mails through the system.
Is there a way to protect an open relay mail server?
Thanks for any info.
