Email Blacklist

I dont mean email, but can you block someone who sends mail repeatly and wont stop? It didnt happen to me, but there is alot of ads on the internet that offer you free things, and what if you did give them your location so they send you the item. My dad says that once you give them the information, they will send you mail all the time.

I would like to keep the same e-mail address but I am getting mail from people in my past that take up too much time to read or respond to. Can I block their e-mail?

I get e-mails from people advertising sex or watches or whatever else and the people I get them from, I know I’ve never given my e-mail address. Is there a way to block my e-mail from getting crap like this? I have two kids that use my computer and they don’t need to hit my mail button and see “Find a f–kbuddy tonight. Please help.

On several occasions, Yahoo’s spam filter has blocked email sent by users and domains to whom I have sent email, including people people in my address book! Is there any way I can go back and see all emails that have been sent to me? Is there any way to ensure that the filter does not block certain people or domains, if it is set up to do so? I’m really frustrated — as some of these emails were very important.
