From what I understand of it - they also require a working abuse
contact email. The idea being that you're not just anyone that can put
together an SPF record and maybe paying some sort of fee makes you more
"real" than SPF. Anyhow - rather than signing up right away I was
thinking about testing the list as a list user and see how white it
really is. And if it's from Barracuda maybe it's already populated with
good data.
I haven't found SPF useful for white listing. I've seen spammers with
good SPF. If I were a spammer I'd have good SPF.
Ultimately what I think makes the best white list is a list of domains
whose FCrDNS is a host in the list. And the list of domains is based on
reputation.
Andhow - my real question is - how to put together the query in Exim
where the query is:
<hostname>.<ip reversed>.<listname>
How do you do that?
