>"The practice of checking the validity of email addresses seems to be lost on many (most?) businesses." Yes, including some that should really know better. I see this issue with more than one major bank. >"Whenever I could find the relevant information, I contacted the various people that send me the original email to correct the information." That's brave. I've had nothing but grief with this - some combination of "Who are you?", "Leave me alone." and "You stole my email address!" in every case. Contacting the sender isn't much better. In the case of medical / financial information it seems to me there should be an easy way to report this to some sort of regulatory authority.
