Two company's merging - email worries

Hi,

Tech info: Windows 2000 domain, Exchange 2000

We are merging with another company and so changing our company name and email addresses.

I have added the new addresses *@newcompany.com to the recipient policy on our exchange server which has updated AD with the new email addresses ready to go.

We are taking on board the smaller company who also run Exchange 2000.  I have created mailboxes for them here and I need to make sure any email that gets sent to their old domain gets forwarded to the new one here.  How can I configure their Exchange server to send all incoming email to our Exchange server?

Do I set their Exchange server up to forward their email to the new domain, or to the external IP address of our MailSweeper server?  Whichever option it is, how do I do it?!

Then, how do I setup our Exchange server to accept it, or is this already taken care of via the recipient policy?

Thank you.

u can add the old and new domain addresses in the recepient policy and then configure the both ip addresses to you exchange external NIC. and remove their old email server from the internet.

your server will accept the messages for both domains, and for those new users u can create a OU in active directory also create a new recepient policy and apply it on that OU only by doing this the users which are in OU have both addresses and accept email from old and new domain.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

That sounds simple enough....I hadn't thought of having their email routed directly from the ISP to our mail server.  When you say configure both the IP addresses, which ones do you mean?

just contact DNS authorities and ask them to add up a new MX record pointing to your Mail server address for the old domain name, it will do the trick.

Before, don't forget to add the new domain addresses in the recepient policy...

in windows 2000 u can assing more than one ip to a single NIC u can configure both ips means the ip pointing to your old domain MX and the new domain MX.

tcp/ip properties click advanced button at the right bottom then configure additional ip addresses as well as default gateways and other settings.

u can also do as Yan said but keep in mind that DNS changes takes hours to replicate. might be you would not be able to get the emails for that time from all or some.

btw.. no need to assign 2 IP addresses... just point both mx records for the 2 domain name to the same IP..

i just said that dns would take some time to replicate with other dns server around the world, it should have to replicate any changes u assign 2 ip addresses or point two mx entries to one ip.
