General email spam or blacklist policy and best practice
this is not related to hosting part i believe, but i know i would get some expert opinion on this here.
when gmail, yahoo or hotmail blacklist or add an address to their spam filter for example email@example.com, does all the other emails also get in to the spam list from that domain? for example firstname.lastname@example.org will also be blacklisted in this case?
thanks in advance
