I think there is a gut perception issue about it; I have no stats, and I
should have. Guilty as charged. Nevertheless, since I am too lazy to
have stats I do manual queries, and the last two I queried (that had an
SPF record) were:
aol.com text = "v=spf1 ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ptr:mx.aol.com ?all"
symantec.com text = "v=spf1 ip4:198.6.49.0/24 ip4:65.125.29.0/25
ip4:206.204.57.47 ?all"
So, bozos such as myself might have a tendency to think something along
the lines of "how good is SPF if AOL can't publish a -all" because IMHO
the only way I would refuse inbound email is a straight fail, not a soft
fail or a neutral.
If perception == reality, the fact that AOL does not have a -all means
nobody does (this is exaggerated, of course, but since AOL has
historically been one of the main domains that have successfully used by
spammers as a source address....)
I have read and understood the charter of the WG, nevertheless there are
plenty of people such as myself that look at MARID and/or SPF as cheap
ways to curb spam and/or phishing schemes, and a soft fail or a neutral
does not do any good to me.
The ten most popular SPF records are:
1 1097 v=spf1 mx -all
2 804 v=spf1 ip4:a.b.c.d/32 ip4:a.b.c.d/32 a ptr mx -all
3 463 v=spf1 a mx ptr -all
4 429 v=spf1 a mx -all
5 325 v=spf1 -all
6 306 v=spf1 a -all
7 171 v=spf1 +exists:CL.%{i}.FR.%{s}.HE.%{h}.null.spf.example.com
-all
8 131 v=spf1 include:example.org ~all
9 131 v=spf1 a mx ?all
10 130 v=spf1 ?all
Interesting. I picked the #4 most popular.
arneill-py.sacramento.ca.us text = "v=spf1 a mx -all"
To some extent I think that #1 - #4 are basically in the same spirit
(the difference being the setups are not the same), and this makes for
the vast majority of SPF records.
