Re: [ietf-smtp] DANE penetration for MTA/MTA interactions

Dave,

I have previously gathered metrics for our outbound sending using DANE (I've 
presented at M3AAWG about this), however, we can't know how much inbound mail 
is using our DANE records.  If you're interested in the outbound numbers, I can 
send those to you.

Subject: [ietf-smtp] DANE penetration for MTA/MTA interactions

DANE has been around for a long time.  I'm curious how much actual use it
gets for email transport.

Is there any sort of subjective or objective assessment of percent of sites or
traffic using it?

Not just DANE records published, but DANE /use/.
