It makes sense to check for that. But having a static routable IP is a strong hint that it could work. Have you more details for that "declaration" you hint at? How is an IP "declared" as "domestic"? > Anyway, if you have to ask, then you probably have A LOT of reading to > do before you have the skill to do it without making mistakes that will > get you blocked or worse. These days blocking goes the other way around. But if you manage to get SPF & DKIP up and running correctly (perhaps also DMARC) your chances are good. Of course, some crappy ISPs (Microsoft, I'm looking at you, outlook.com and hotmail.com) insist that you register *with them directly*, it seems. But hey, that's Microsoft. Cheers -- t
