I am having some issues sending email that I beleive are related to SPF record.
Here is my setup. I am in the process of implementing an exchange server thus moving away from hosted email. I am using my exchange as a smtp server for most of the user (I have a lot of remote user that I have not converted yet). some recipient are rejecting emails and I am pretty sure it is due to SPF. My exchange as a FQDN of exchange.mycompany.com and we are sending with email firstname.lastname@example.org. The MX records have not been changed. How can I set a SPF record on the exchange server so that SPF filters will not flag us a email spoofers?
