Notification failure notice

  1. Hi my client is having issues receiving notification emails.

    I've tested using my personal email address and i receive the notifications fine but for some reason the client is experiencing issues. I received the following 'Mailer-Daemon' error but then the client said they received the notification afterwards anyway.

    "Sorry, no mailbox here by that name. (#5.1.1)

    --- Below this line is a copy of the message.

    That link is really the summation of our knowledge related to troubleshooting notifications. What have you tried on there? Have you tried switching it to SMTP?
