Interesting... According to their own "Top Email Senders by Domain",
13 out of 25 domains publish SPF records and zero domains publish SID.
Yesterday:
SPF: 6195 out of 27775 IPs (22.3%)
SID: 0 out of 27775 IPs (none)
DKIM: 3983 out of 27775 IPs (14.3%)
Last 30 days:
SPF: 9948.36 out of 33108.3 (30.0%)
SID: 0 out of 33108.3 (none)
DKIM: 4031.68 out of 33108.3 (12.2%)
Perhaps more companies published a SID record but according to their
own stats this is not significant.
I'm going to count their spf1 and spf2 records as well. WIP.
I wouldn't bother - they only have 38,125 spf records listed, a tiny
fraction of the 1,000,000 or so that are out there. And because of their
need to identify the bad-guys, they are probably skewed to be looking
more at spammers than a genuinely representative sample, so the results
are hardly significant.
And having just checked their reporting of some domains and IPs that I know, I find that
the results seem to be quite badly wrong.
Slainte,
