(following up to my own post...) Here's some good data to re-enforce my opinion on this. Accurate: (email from 192.249.57.241 aligns, email from 65.20.0.12 fails) http://domainmail.org/dmarc-reports/yahoo.com%21netcoolusers.org%211485043200%211485129599.xml Not accurate: (email from 192.249.57.241 permerror) http://domainmail.org/dmarc-reports/yahoo.com%21netcoolusers.org%211484784000%211484870399.xml -Jim P. _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
