Setting up a mail alias

[Vanalden]

Main Domain: Sample.com.au
Secondary: Sample.com

I want to make my secondary domain alias of my main domain but unfortunately I can't change my secondary domain dns MX records into g suite because my secondary domain have email accounts that changing MX records might cause problem to the existing accounts.

Note: My Primary Domain connected to my G Suite so I want to change my Secondary Domain MX Records to G Suite.

Please need help, Thanks!

If your secondary domain has email accounts that are not on the primary domain and you can’t move them, then you would have to create the words on the current mail server from the secondary domain to the primary domain. Alternatively if you want everything in Google Suite you would need to create the mail accounts that are only on the second you mean on the primary domain within Google.

What about the current website using the secondary domain will there be a conflict if ever I changed the MX records?

Thanks

Email / Website records are separate - the only issue you would ever run into is if you had setup something like mail.yourdomain.com as CNAME pointing to @ and then you change the root @ IP address
