Diverting smtp traffic
Hello All
I have an old e-mail server that is still accepting e-mail for some
domains. The MX records for these domains are controlled by
other parties and getting them changed would be a bit of a mission.
At the moment this server forwards all e-mail to my new e-mail
server. However in the process I loose some control. Particularly
the anti-spam, anti-virus configurations etc are not on the old server.
What I would like to do is forward all TCP traffic on port 25 on the
old server directly to the new one. I have tried "ipmasqadm --
portfw" but there is no masquerading involved and it does not work.
I could also user "redir" or "xinetd" but these will hide the
originating server IP address from the receiving server. That would
mess up RBL controls and may even open up an open relay!
Has anybody done this before? The machine is running potato with
a 2.2.19 kernel.
Thanks
Ian
