How do we setup IBM Notes/Domino to receive email from two different domains?

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

Thanks

Sounds correct, aside from any DNS changes, amendments to any anti-spam/virus or other general mail routing that should do you for Notes.

You shouldn't need to add the email address to each person document though as long as it will match with your name format together with one of the alternate names, i.e. if the full name is Steve Knight/Dragon-IT then it will match with steve.knight@domain1.com, steve.knight@domain2.com etc. if they are in the global domain document.

You can set the internet address in their person document to any of the potential combinations of course to use for their main reply address, and if you want other addresses such as other alises they had before just add them to the full name field.

I suggest to make sure you are happy with it (aside from getting someone in!) is buy another domain or one not yet used and do the same, for the matter of <£10 etc. point MX to your domino server and do exactly the same as you are going to.

Come to that just add madeupname.com to your aliases and test it using a mail client pointing directly at your domino server for sending smtp or usign TELNET.

Easy option though is just buy a real domain and can prove comms in and out then through any additional kit it might need to pass through too.

We were able to successfully perform the migration.  Thank you very much for your help and for pointing out the Anti-spam amendments.  That was something I had originally overlooked.

No worries, glad it helped.  Domino makes this very easy really but always best to be sure, we have some companies with many different domains handled in this way.
