Hi Team, In my test lab, Am using exchange server 2007, having two separate organization. The Mail Flow with in Organization is perfect. Now i would like to send email from one Organization to another. Example (from ABC.com domain to xyz.co.in) How can i achieve that ? My setup is : Am using VMware Workstation , Both the organization in the same LAN and Same subnet. Both the DC are Pinging .and NO Internet Connection in my setup. What can i do next ? Do i need to create any trust between the organization? or Accepted Domain i need to add? Could you please help me to achieve this? Thanks in Advance

Configure Send and Receiev connector . To properly emulate Internet Connectivity you shoule have proper DNS & MX records.

Hello Khoj Thanks for your update. This is my test Environment, where there is no internet connection and hence no MX record required for my setup.

But you DO have a DNS zone for those domains in your lab, right? Configure them as you would if they were public DNS servers on the Internet. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Rich, With out Internet can't we achive this? , I think can we create a trust between the two forest.... can we achive by this way?

You said you want to send mail from one organization to another. The assumption was that you want to emulate the sending of e-mail between two systems that are unrelated to each other. The way to do that is to configure a DNS zone for both organizations (which you already have) and then to have the DNS in organization A use organization B as a DNS forwarder, and vice-versa. Then add the necessary MX, TXT, etc. record to each DNS. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Team, Still my Test environment is not working.. i had created the MX Record point to the another Hub server of the other Forest and Vice versa in DNS. Created a send connector in Domain (A) and Receive Connector in B Still the mails are stacking in the queue..

Created a send connector in Domain (A) and Receive Connector in B Still the mails are stacking in the queue.. For what reason are the messages failing to be delivered? Is there any evidence in the SMTP protocol log that shows a connections was tried and rejected? In forest A, can you use nslookup and find the MX record for the DNS domain of forest B? Does the MX record use the A record of the SMTP server in forest B? Can you "telnet <forest-B-smtp-server> 25" from the HT server in forest A and connect to the correct server in forest B? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Rich and All, Thanks for the update. My issue has been solved. Here are the steps i did Two Forest A (org1) and Forest B (Org2) Goal : Email should flow between the above forest (Between two Org) 1. Created the trust between two org(Org1 and Org2) 2. Created the Secondary DNS zone in each ORG DNS. 3. Created the MX records in ORG 1 pointed to the ORG2 HUB server and Vice Versa. 4 Send the email from Org1 to org2. Mail has been struck in the queue saying that, there is no Primary Connector found to send the domain(xyz.com) 5. Created a send Connector to Internal and added the * then added the smart host as org2.hubserver Queue has been cleared but got the NDR saying that, the Client has been rejected. 6. Point to org2 Hub Transport server receieve connector and tick the ANONYMOUS users in the authentication tab. EMAIL got delivered to ORG2. 7. Created the Send Connector from ORG2 like ORG1 and did the same in the receive connector in ORG1. Emails are flowing between the two organization. now i have big doubt ,whether 1. do i need to create a trust between the forests. 2. Do i need to Create the Secondary DNS zone in each ORG DNS. 3. Do i need create the MX records in ORG 1 pointed to the ORG2 HUB server and Vice Versa. or Send and Receive Connectors are enough, How ever am going to test this anyway with craeting the trust, DNS, and MX.... Could you please clarify before that? Thanks for all support once again.!!!!!

Created the Secondary DNS zone in each ORG DNS. That's one way to get the DNS information into your organization, but you'll get too much information. You have no reason to know about the other organization's internal infrastructure. To deliver mail you need only the MX and A records. That's why I said to creadfe a new zone in forest A for forest B's domain, and vice-versa. You can even create a "stub" zone that just directs DNS to the "other" DNS. That way you don't have to worry about DNS zone replication (which is something you won't be doing on the Internet). >3. Created the MX records in ORG 1 pointed to the ORG2 HUB server and Vice Versa. Okay. >4 Send the email from Org1 to org2. > >Mail has been struck in the queue saying that, there is no Primary Connector found to send the domain(xyz.com) > >5.

That's not surprising. Unless you've created another Receive Connector in forest A that allows forest B (and vice-versa) to use anonymous connections this is exactly what would happen if these machines were trying to receive e-mail from the Internet. >6. Point to org2 Hub Transport server receieve connector and tick the ANONYMOUS users in the authentication tab. But you don't want to do that unless you also want anonymous connections from within the organization to use that Receive Connector. >EMAIL got delivered to ORG2. Good. >7. Created the Send Connector from ORG2 like ORG1 and did the same in the receive connector in ORG1. > >Emails are flowing between the two organization. now i have big doubt ,whether > >1. do i need to create a trust between the forests. How do you propose to do that with other companys??? :-) If your excercise is to create an "Internet-like" environment they you cannot have any knowledge of the other organization except what's published in DNS. You only need a DNS zone in both forests for the "other" forest, and then you only need to create "stub" zones. >2. Do i need to Create the Secondary DNS zone in each ORG DNS. You'd have a real problem doing that on the Internet. :-) For your testing you'll need to direct your DNS to the "other" DNS. On the Internet that would be done using "root hints". In the lab (and in production, if you want to do this) you can use "stub" zones. >3. Do i need create the MX records in ORG 1 pointed to the ORG2 HUB server and Vice Versa. No, you just need to get forest A's DNS to use forest B's DNS when it wants to find something in that domain. Without root hints, you'll need a "stub" zone. >Send and Receive Connectors are enough, How ever am going to test this anyway with craeting the trust, DNS, and MX.... You need to understand how to get DNS to do you bidding. >Could you please clarify before that? See above. :-) --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
