This list does not seem very active, but I'll try it anyway -
we are an email filtering service so we "sit" in between our customer
and people that want to send them email. (we obviously use MX
redirection).
We have a situation where "adjoli.de" wants to send a perfectly legit
newsletter to my customer, but is being rejected by the customer
mail-server due to our servers not being listed by the SPF record
for "adjoli.de":
"v=spf1 ip4:194.29.239.0/28 ?all"
The customers mailserver is smart hosted by a provider, nothing unusual
about it. The question is - is it _right_ to plainly reject the email
from "adjoli.de" when the spf evaluation says "Neutral" ?
RFC 4408 is very clear on this. Neutral MUST be treated the same as None,
so unless they are also rejecting mail from domains with no SPF record
(this would not be likely at all), what they are doing is clearly NOT right.
Julian is correct about they two general solutions for this kind of problem.
