I have Exchange server 2010 and config with SPF/SenderID. I have fortimail. Fortimail is support with DKIM. the reason that I want to implement DKIM with fortimail is:
I have some of applications, I want to sent reports by using external email khemarin@gmail.com, my exchange server domain (khemarin@hello.com). I configure relay with my exchange server, so the email can sent successful.
My problem is: most of email mark as spam. that sent by khemarin@gmail.com
Do you have any idea or solution for me? After I configure DKIM with Fortimail in my environment, the email still mark as a spam?
BR, Khemarin
