How do I keep it from applying this to my own clients such as:
# this protect my server from being an open relay, relay_hosts are
IP's that did popb4smtp
accept hosts = +relay_hosts
accept hosts = +auth_relay_hosts
endpass
message = authentication required
authenticated = *
deny message = relay not permitted
# this is how I restrict port 587 to relay for my clients
accept hosts = +auth_relay_hosts
accept hosts = +relay_hosts
condition = ${if eq {$interface_port}{587} {yes}{no}}
endpass
message = relay not permitted, authentication required on port 587
authenticated = *
I don't want to reject clients with no reverse DNS that have used auth
smtp or are in relay_hosts list. How do I do that?
