Hi, I'm wondering what people's opinion is on domains like verticalresponse.com and vresp.com, and others, that seem to distribute mail to anyone who wants to spend the money to buy a list from them. Constantcontact might be in this same business, but it seems like their reputation has slightly improved over the past few months...
While some of the mail from that sender seems legitimate, other mail clearly isn't, but it has the same header as a legitimate mail, making it very difficult to properly train bayes or otherwise accurately determine that it's indeed spam and it should be discarded. I know this issue has been raised on this list before, but is there any more information that people might have with regards to their policy on mail such as this? Thanks, Alex
