We are in the process of incorporating a new company. Let's just say that their domain name is "newcompany.com" and all their email addresses are as such (ex: BobSmith@newcompany.com)
We are creating them new email accounts on our Domino/Notes system (Lets use @acme.com for our domain name in this example). So when someone emails BobSmith@acme.com they will now be able to receive email on our system and will continue using this going forward as the primary email address.
We want to eventually shut down their servers but we want to keep their old email address alive so that any emails sent to "@newcompany.com" will route to their primary Domino mail file.
These are the following steps we are going to perform, could someone please verify if these are correct or if there's something we're missing?
1- Create an alias in every person document (ex: add BobSmith@newcompany.com to the person document of BobSmith@acme.com)
2- Change the MX records for "newcompany.com" to point to the same place as "acme.com"
3 - Add "NewCompany.com" to the "Alternate Internet Domain Alias" field of the Global Domain document
