Strange e-mails from unknown addreses w/ no content?

I have received numerous e-mails marked "undeliverable", Mailer-Daemon - failure notice, Postmaster - mail delivery - failure etc., etc., - If anyone can shed some light I would be grateful. As usual u can't get a human to answer on Yahoo's telephone # 1-866-562-7219

You are being spamed by bots from someone whom you have angered in some way. DO NOT open anymore of the failed emails. Mark them all as spam and delete them. If they do not subside in a few days you will need to establish a new email address.

watch it - stuff like that is usually a well disguised carrier of a virus.

You have sent an e-mail out to someone and it couldn't get delivered to that person.

just report it as spam and you will not receive that on inbox...

I get that if I send an email and its undelierable cause i wrote the email wrong hpoe this helps

u get that if u send something to an email address that doesn't exist so check that you are sending everything to the right email addresses

You are sending e-mail to a box that is closed, is full and will not receive, or the address is wrong.

If you are Bcc, then you need to go to a better source for your spam mailing lists.

You won't have this problem if you're communicating with people who want your correspondence. Also, people may choose to block your incoming, with the options that Yahoo provides.

What you're receiving is your own e-mail back.

It is just a notice to you that your mail didn't get to the other person. I have had that happen quite a few times. You have sent emails to some people or places and they could not deliver them.
