I'm going to add an SMTP Spam/Viruses filtering Gateway in the DMZ to protect
an internal Exchange server, but i'm looking for the right domain and sub-domain
configuration changes to do.
As far as I know, my SMTP gateway should be "host.domain.tld" and my internal
Exchange server "host.subdomain.domain.tld".
The problem is, my present Exchange server is "host.domain.tld" and changing
it would require changing the Active Directory by creating a subdomain,
moving all users/computers there, etc...
I read "tons" of information that are very detailled on configuring the
SMTP filtering gateway, but not on the DNS part. Isn't it possible to do
it in a more simple and safe manner, and, if not, has anyone already done
it successfully ?
More information on the network :
WAN : leased line and router, 128 Static IP Addresses
DMZ : where the HTTP proxy resides and where the SMTP Gateway is ready to
be "activated" (RH 7.3, postfix, spam-assassin, amavis and CA inoculateIT6)
LAN :
1x W2000 Server Domain Controller for "domain.tld"
1x W2000 Server Exchange 2000 server for "domain.tld"
Thank you for your help
