People at large mail systems tell me SPF is not very useful. That is particularly true these days when so much mail is sent from large shared systems which makes it easy for any of their customers to SPF spoof any other customer. >If SPF support were eliminated from DMARC, what actual change in DMARC >utility would this have? The most likely effect is that people who have a checklist for their mail system that includes "implement DMARC" which they satisfied by publishing an SPF record and nothing else will be sad. But I can't feel very sorry for them. R's, John _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
