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 protected] does not designate 1.1.1.1 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 protected] to [email protected] 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.

Office365 SPF record has too many lookups

For some utterly ridiculous administrative reasons we've got a split domain with one mailbox on Office365 which requires us to add include:outlook.com to our SPF record. The problem with this is that that rule alone requires nine DNS lookups of the maximum of 10. Seriously, it's horrible. Just look… >>> More
