It isn't a big deal if it is a person; I let them know, they fix it. The big problem I am having is with companies and websites. These emails are often no-reply, which means I can't send back a quick note. I got someone's credit card bills for three months before I realized there was nothing for it but calling the company (I tried a couple of emails first). Recently I got a notice about someone's kid signing up for a website. I don't have any option but to hit the response button, and tell them that I first have to say I am that kid's parent or guardian. I didn't know where to go from there. Today I get an invoice from a cable company; it is for a different state. I can't reply. I go to the online support, they tell me my only choice is to call the sales office. I gave in for the bank, but I am not talking to someone else's cable company. Is there any way to make emails to an improperly formatted gmail address bounce or do something else obvious? Is there a technical solution I am overlooking. I doesn't happen that often but it is an increasing PITA with no-reply email addresses. I hate just setting up a filter because that cuts off these other people who made a typo or had someone not enter something correctly, but it is looking like the best choice. It isn't spam, but it isn't my meat."
