How do you make it so port 587 ONLY works for authenticated clients,
and my popb4smtp clients?
I have tried this.
# to restrict port 587 to authenticated users only
# see also daemon_smtp_ports above
#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 = *
domainlist local_domains = lsearch;/etc/virtual/domains
domainlist relay_domains = lsearch;/etc/virtual/domains : localhost
hostlist relay_hosts = net-lsearch;/etc/virtual/pophosts :
/etc/virtual/relay_ips : 127.0.0.1
hostlist auth_relay_hosts = *
Pophosts contains a list of IP's that have poped in last 15 minutes.
Relay_ips are just a list of IP's I own and trust. When I enable it
the pophosts are not allowed on port 587.
