OK, I've sent you an alternative email address. But all the addresses I have are from the services you recommend not using. Why on earth would AOL, Yahoo, and gmail all reject messages from the domain kvstool.com, while servers from businesses etc. would let these messages go through? (This isn't a rhetorical question; I'm genuinely curious. And my curiosity is compounded by the fact that I've received numerous less important messages --- notifications of subscription renewal etc. -- from KVS Tool in the past. Why would they reject the one message I really need?)
