I'm using Google Apps for my domains email, and have the Google suggested SPF set:
"v=spf1 include:_spf.google.com ~all"
This works as expected. In certain cases though, my web app sends emails to users (exim4) also. The problem I'm having is that when the server sends emails, the SPF soft fails:
Received-SPF: softfail (google.com: domain of transitioning firstname.lastname@example.org does not designate 22.214.171.124 as permitted sender) client-ip=126.96.36.199;
I'm confused how I enhance my above SPF to permit my domains IP to send emails also. I'm not sure if I need to add to the above SPF, or create a second one.
Any help would be appreciated, Thanks
