MX record

[Bill Clery]

The outside mail will still have to come to the machine with the public
address - so it must continue to run sendmail.

This machine could forward the mail onto another machine with an internal
address.  Use the virtusertable to redirect the mail to a private name and
put the private name MX in your DNS.  You may even be able to put a line in
you virtusertable like:

*@mypublicdomain.com   *@192.168.30.4

This would avoid any internal MX line.  not sure that's legal.

Hello ,

We have firewall (used for natting) and inside our LAN only
we have in one machine where public IP natted to private IP
the DNS server and email server. Now I want to forward the
emails to a different machine.

Now my qn is can the email server be given the private IP or should it
also have public IP natted to private IP

present entry in named.hosts

IN MX 100 www.cdfd.org.in.
cdfd.org.in In A 210.212.212.3

Now I want to change to

IN MX 100 mail.cdfd.org.in
mail.cdfd.org.in IN A ?

? --> can be a private IP or not



pls clarify my doubt

Thanks
