One of our clients runs an exchange server (2003), and are having trouble sending to hotmail addresses.
I understand that to resolve this problem, we need to create an SPF record for the domain.
However, we host the domain with 1and1 who I beleive dont support SPF records.
I have read up on external DNS hosting - for example zoneedit.com.
However, Im not sure if this will even work - I take it I would have to point the domain in 1and1 to external dns (ie zoneedit account), but then how would I point the A record (website) back to 1and1 - baring in mind we have a hosting account and not a dedicated server. Is this even doable?
What are the alternatives?
And do Hotmail REQUIRE an SPF record by default, or is it just useful if the domain has ALREADY got blacklisted?
