I want to redirect email from
domain2.com. The problem is that the mail for
domain2.com is hosted by Google Apps. All my employees have two email accounts:
employeeX@domain1.com hosted in my office and
employeeX@domain2.com hosted by Google Apps. I will turn off my office email servers when I'm sure that all the mail is redirected, so they only need to use one email account.
I don't know if changing the
MX record for
mail.domain2.com is enough, or do I have to do something else?
