Sorry, I disagree. Vendors, especially those who have been involved in this for a long time, are in a prime position to provide appropriate guidance and influence. And at least from where I'm sitting, a substantial portion of the customer base is at least listening to what we tell them. And sometimes "customer" is itself referring to a large and influential ISP. > So yes, when I read those comments, the eyes are rolling. I have no doubt *you* think the ideas are absurd. But please stop speaking for all SMTP vendors, because I for one think you're exaggerating, and have experience to the contrary. Perhaps some other vendors would like to weigh in. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
