We just migrate our main domain to a new one. (@olddomain.com -> @newdomain.com)
Now we want that people who send emails to any account in @olddomain.com, receive automatically a message like "the new email address for this person is whatever @newdomain.com"
- We don't want our old domain as alias of the new.
- We already are using two Google Apps account for both domains, but we are looking for a solution with or without Google Apps.
Thanks in advance
