Hi, We went through this a couple of months back when we switched to a .info domain. We're running a single Exch 5.5 with around 50 mailboxes. Apart from setting the MX record in the DNS, the exchange server only needed 2 modifications: 1> Add the new domain in the Routing field in the Internet Mail Connector. This will allow you to recieve any inbound mail errors for that domain. 2> You'll have to go through each Mailbox and add the new internet e-mail address manually. You might also want to set this new e-mail address as the Default Reply Address to make the users send using the new e-mail address. That's it. I don't know if there's anything else which needs to be done, but ours has been working fine for a few months now.

We have only one domain, one site and one Exchange server. There is a pop3 server involved in this too. Our Exchange 5.5 server is set up to send Internet mail through an external SMTP gateway that also handles all incoming mail. Has anyone else gone through this and could you please let me know what I will need to do on the server to get it changed. When we start the project we will have 6 months that we can operate under both names before the old name comes up for grabs. Thanks in advance Byron ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: andreacoppini@xxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
