It turns out that I changed a server domain and did a page update, to the mail I can continue to enter via google, but this new mail does not arrive, it gives me the sgte. eror: the address was not found, your message was not delivered to [email protected] because the address is not found or can not receive emails from the remote server: 550 not your user here. my question is for this I must create an email with the same domain on my server? Another question is if I do this, will not the old emails be deleted? If so, is there any way to back up the mail data well? since he has this I can still enter and see the old emails and send emails, but I can not receive new emails at that address
