good day everyone,
i have a client that is having an issue with NDRs between their google app mail server running on a linux box and an external Exchange 2003 box, the email is being sent by the exchange 2003 server, for some reason only one domain get's bounced back. everything else is getting through.
the client seems to think it's an SPF record issue, if that issue does exist, what configuration could possibly be missing, what can i have him check to make sure all is configure properly?
this will help us eliminate the obvious things and move on to more advance troubleshooting. i will ask them for one of the bounce back message and post as soon as i have it. thank you
