I installed SPF on my LAMP server with postfix. But for some reason, I get this error
Received-SPF: softfail (mta1070.mail.re4.yahoo.com: domain of transitioning firstname.lastname@example.org does not designate 126.96.36.199 as permitted sender)
I have two questions:
1) how do I trouble shoot this error
2) I've been looking through my configuration files in an attempt to change email@example.com to firstname.lastname@example.org because anotherurl.com has the correct SPF TXT records. Where do i go to change this? I tried editing myhostname under /etc/postfix/main.cf, but it didn't do anything.
