A lot was from my computer to the smtp server..the rest was just mine. It is really simple, not much in there at all. However.... I have full control over my ips...almost. The datacenter has to add a PTR record for each domain. They said they only need to add mydomain.com, only one record per ip and not anything like mail or ftp, etc. Doing dns checks at pingbilly (strange ass name) Show everything is groovy. http://pingability.com/zoneinfo.jsp?domain=bobhoffman.com I think tonight we will see about spf. I also read that sometimes it takes a while, like a week or so before yahoo will respond joyfully to your spf. No instant happiness it seems. I should just send letters via usps to yahoo and have them scan them to their users....be easier.
