Ok, so i have an issue, i have port 28 configured, with no SSL or auth, the auth mode is always allow. What I want is that port to get data from my spam solution. if its sent to that port it should accept it without auth, however, i am finding tha I still need to allow it to relay even on that port? why is that?
Just do SMTP properties > Relay > Allow Relay for privileged IP ranges. Then set the spam solution IP. No need to mess with ports unless you want to lock it down even more with a firewall based on IP+Port.
