My mailserver is behing a firewall that also does nat tranlastion. So
the inside has a dmz zone. When you hit from the oustide you hit the
outside / public ip numbers. You are hitting the firewall box. Then
going in to the dmz zone. The firewall is setup to route the proper
ports back and forth to the inside. Port 25/110 has two sets of rules.
One incomming and one outgoing.
69.69.25.125 port 25 = 172.16.0.10 port 25. (both ways)
172.16.0.10 port 25 = 69.69.25.125 port 25. (both ways)
(I don't do firewalls so my answer is limited.)
example:
(this is just a example with example numbers)
fw: (69.69.24.123)
ext pub ip for mailserver: (69.69.25.125)
dmz: (172.16.0.1)
mailserver on inside in dmz zone: (172.16.0.10)
So for the setting via proxy / inet.
Inet = localhost, 172.16.0.10
(WHAT DO I SET THIS PROXY TOO?)
Proxy = 172.16.0.10 ???
Next question. (I can post more of the log if needed)
This looks like a open relay. THis is the beginning of spam hitting my
server then it will get routed out to other mailservers. I changed a
few things to protect myself in the log file. But any ideas how to
stop this? I did post my configuration file a while back and check
most everything everybody was kind to sugguest. Including this proxy
setting I'm asking about. Notice the strange long id in front of the
www.myserver.net If it is a normal e-mail like twink...@myserver.net
it gets bounced.
