Let me post here a rant on, IMHO, SPF-abuse practice:
Both mail.ru and yandex.ru are completely free email service
providers, but compare their SPF:
mail.ru. 6H IN TXT
"v=spf1 ip4:194.67.57.0/24 ip4:194.67.23.0/24 ip4:194.67.45.0/24 ~all"
yandex.ru. 1H IN TXT
"v=spf1 ip4:213.180.192.0/19 -exists:%{l}.%{ir}.yandex.spf-check.yandex.ru
?all"
Hint:
mail.ru creates problems for legitimate users;
It is their domain, they can do with it whatever they like. If they want
you to use their servers, they have every right to publish such a
record. You're not paying them (free service, remember) in any way, so
what makes you think you have a right to send messages with a MAIL FROM
from their domain? What makes you think you have a right their service
at all?
yandex.ru creates problems for spammers, but NOT legitimate users.
I doubt that a default SPF softfail will lead to an awful lot of
problems. Mail *may* be scrutinized more extensively, but in reality
many recipients will treat SPF pass/softfail/neutral/none in very much
the same way.
Assumptions of the hint:
recipients have 'proper' SPF implementation.
Please clarify, because a 'proper' SPF implementation (whatever that may
be) will not outright reject a message for a SPF softfail result alone.
So what is your problem?
P.S. If one thinks that mail.ru is alone in such a policy for being
what it is, one is well mistaken.
Hotmail? Roadrunner? It's not all that uncommon to have a record that
ends in '~all'...
