SPF not correct

Hello All, I was testing my mail server with this email testing service and noticed this message fail: local="u.fukt.lol: Sender is not authorized by default to use 'u.fukt.lol' in 'helo' identity (mechanism '-all' matched)", authority="Please see http://www.openspf.org/Why?s=helo;id=u.fukt.lol;ip=140.82.19.182;r=ts11-do.checktls.com" I tried going to the openspf.org domain it mentions but it seems to be offline… Can anyone help with this?

Try adding a hyphen to the domain:

http://www.open-spf.org

I did try this, but I just see a webpage that askes me to put in “mail from” and “sending ip” I enter the sending ip and mail from and it just reloads the page.

And most importantly, they are not out to sell you something like many of the other tools mentioned in this thread.

I don’t know if it is the only one that’s worth using but it is a go to that I use time and time again, it’s simple, fast, and accurate.
