One of my client change their email to Gmail app, and I found one problem that I dont really know how to solve ...
When I want to send mail to my client, if the email didn't exist in the DA mail account exim will reject the mail (system cannot found the account to send, but the real mail server is Gmail MX)
My client still use our web and DNS service, so since my client shift their email to Gmail, I cannot send mail to them through the DA server in the same machine.
Is there any solution let the server knowing the client no longer use the localhost MX service ? (hope "she" won't break heart when hear this news)
