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 email@example.com does not designate 220.127.116.11 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 firstname.lastname@example.org to email@example.com 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.
