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?
