>From a post I made to another list some time ago: "My general advice WRT to VPS/colo/hosting outfits such as Softlayer, Limestone, Sharktech, Hostnoc, Colocation America, Colo4, SingleHop, Liquid Web, ServePath, GigeNet, WholeSale Internet, FDCservers, CarolinaNet, Hurricane Electric, et al is to SMTP block their entire IP space and then whitelist sender addresses if/when necessary." That is by no means of a complete list of outfits that are persona non grata at many sites. Those listed above, and many others, have a reputation for hosting snowshoe spammers, either willfully or by ignorance or negligence. What outfit are you moving to? What are the IP addresses they have assigned you? Depending on your response to either of these questions I may be able to tell you instantly whether you should pick another outfit to host your gear. For anyone planning to stick a rack of mail sending hosts into a colo facility, you _must_ research the reputation of said facility long before signing a contract and turning the key on the forklift. This is usually called "due diligence". -- Stan
