Can someone please help me determine why the email my sister sends to me (Verizon to Roadrunner) comes back to her with this message.� The email is actually sent, but she gets this delivery failure notification (below).� I'm wondering if its a Verizon problem (there are LOTS of Verizon problems ), or if the email has too many replies listed on it. She & I email back & forth all day using the same email. I've cut & pasted below the notice she receives.� Thanks for any help you can give me.
