Sorry, I did but it was in response to someone else's response yesterday. (except for the telnet). I have made so many changes.....this is how I am configured. I am not going to change anything else. Your time is most appredciated.
This is a windows 2k AD network using DNS I have external DNS running on windows 2k I have internal DNS running on windows 2k I have added a hosts entry on both mail servers that point to the other using internal IP address to the "mail.respective_domain.com". Exchange server localhost name of exch1.mylocaldomain.local primary dns in IP config points to my local network's dns server One of the mail domain's it serves is mail.erinhope.com (this is the mx and A record name on external DNS) has hosts file entry of mail.erinhhope.com to local address (10.x.x.x) Imail server localhost name of Imail.mylocaldomain.local primary dns in IP config points to my local network's dns server One of the mail domain's it server is mail.aquesthosting.com (this is the mx and A record name on external DNS) has hosts file entry of mail.aquesthosting.com to local address (10.x.x.x) My internal network DNS server as a forwarder set up for external DNS server of ISP. There is only one zone in my internal DNS server which is "mylocaldomain.local". There are no zones for aquesthosting or erinhope My external DNS servers are hosted by myself and have zones for both aquesthosting and erinhope. Both have MX and A for their respective "mail." I run all this behind an MS ISA firewall server >From EXCHANGE server: Ping internal IP of Imail - good Ping network hostname of imail (Imail.mylocaldomain.local) - good Ping internet MX/A hostname of "mail.aquesthosting.com" - UNKNOWN host Tracert INTERNAL IP of Imail - returns A record name of "mail.aquesthosting.com" [10.x.x.x] (not external IP) Tracert INTERNAL hostname of Imail "Imail.mylocaldomain.local" - returns A record name of "mail.aquesthosting.com" [10.x.x.x] (not external IP ) telent to mail.aquesthosting.com:25 or 10.x.x.x:25 - both return "could not open connection to host" >From IMAIL server: Ping internal IP of Exchange - good Ping network hostname of Exchange (exch1.mylocaldomain.local) - good Ping Internet MX/A hostname of "mail.erinhope.com" - returns internal IP of Exchange server (10.x.x.x) Tracert Internal IP of Exchange - returns A record dnam of "mail.erinhope.com" [10.x.x.x] (not external IP) Tracert Internal hostname of Exchange "exch1.mylocaldomain.com" - returns A record name of "mail.erinhope.com" [10.x.x.x] (not external IP) telent to mail.erinhope.com:25 or 10.x.x.x:25 - both return "cold not open connection to host" -----Original Message----- From: Len Conrad [mailto:[EMAIL PROTECTED] Sent: Friday, July 04, 2003 12:10 PM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Exchange 2k and Imail >a split DNS setup. What DNS software?

I never seen this fail and everybody uses it all the time to short-circuit DNS resolution. Anyway, you didn't answer my question about what happens when you ping, traceroute, telnet:25 from each machine to the other's IP (not its hostname). > However, no other entries for those machines. What should my internal > DNS look like in order to resolve my two external mx/A records. If you use DNS to resolve, it's stupid simple. You set up the MX records for each domain to point to MX hostnames, and then put in A records in each exchange or imail zone: in the exdomain.com zone: mx.exdomain.com. A ip.ad.re.ss in the imdomain.com. zone: mx.imdomain.com. A ip.ad.re.ss But in hosts file, the same thing: ip.ad.re.ss mx.exdomain.com ip.ad.re.ss mx.imdomain.com The hosts above asssumes Imail will find the above mx hostnames in DNS, then resolve them to A records in hosts file. If you don't put MX records in DNS, Imail will try to send to the A record for @recipient.domain, so you would need to add A records to hosts file: ip.ad.re.ss exdomain.com ip.ad.re.ss imdomain.com where all the above IP addresses are the IPs of the Imail and Exchange boxes.
