Hi Roger, I'm not sure that your xamax.com.au SPF details are good.
xamax.com.au: "v=spf1 *ip4:103.27.32.5* +include:retailspf.smtp.com ?all" retailspf.smtp.com: "v=spf1 ip4:192.40.160.0/19 ip4:74.91.80.0/20 ~all" but the sending address at syd.hostingplatform.net.au is 103.27.32.232. You could try changing the ip4:103.27.32.5 to ip4:103.27.32.0/24. You might also want to set up a DMARC record so that you can receive reports of messages that fail SPF/DKIM/ARC checks. Yahoo is one of the fussiest, but also seems to permit the most real spam...
