Dear all at SPF-help, Conundrum: user <at> un.org posts a message to the email list server geneva-web-group <at> googlegroups. Google Groups then sends a group email, marked From: user <at> un.org, but sent using a Google mailserver. The SPF record at un.org does not designate Google as a permitted sender. My ISP blocks the email (dotster.com / mail3.dotsterhost.com - quite strict on RFC and SPF imperfections, for example will <fail> on an invalid SPF record). Received-SPF: pass (googlegroups.com designates 209.85.146.244 as a trusted SMTP server) Received-SPF: fail (un.org does not designate 209.85.146.244 as a permitted sender) Any ideas? (Full headers of sent mail below - with sender's name changed - email retrieved from a Death2Spam mail relay server).
