Exchange 2003 and Google Apps NDRs, Issue wirth SPF
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

Is it the google app mailserver that is sending the mail to the external exchange?
ASKER
sorry for the delay, yes it is. the client has their email hosted with google apps and they are trying to send to a domain with an exchange server.
ASKER
still looking into this, any ideas?
