there is probably no need to actually integrate anything in ispconfig, but i would suggest adding it to the perfect setup guide (using postfix) so people will install it my default
Yeah that would be good to have. I have figured out how to add it to Ispconfig as a template so when you add a new domain it automatically adds the spf record, still trying to figure out how to add the spf/spf file so far it only show spf/txt when testing it.
