That's a pile of money on the line for these guys.
Stephen, thanks for your generous reply, and your insights. It does seem to me, though, that when megabucks are riding on additional bandwidth, and if Yahoo is serious about controlling spam, they might start by putting some resources behind putting their own house in order. Someone, maybe it was you, posted on this forum earlier that perhaps 90% or more of spam with a yahoo.com origin (or one of their international DNs) actually _does_ come from Yahoo and that their response to abuse notifications is abysmal to nonexistent. So it looks to me as if one of two things is happening here. Either the right hand doesn't know what the left hand is doing (or not doing), or this is a blatant, cynical attack on network neutrality designed to push people toward Yahoo's own list service. Has anyone seen or heard any figures on how much this DMARC fiasco has cost Yahoo in terms of the number of email end-users who have left their service? Someone mentioned that it was substantial enough to probably get their attention. -- Lindsay Haisley | "Everything works if you let it" FMP Computer Services | 512-259-1190 | --- The Roadie http://www.fmp.com | ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
