That says the status is a SOFTBOUNCE, which means it is normally a temporary issue. The three most common causes of those are:

  1. Mailbox is full (over quota).
  2. Recipient email server is down or offline.
  3. Email message is too large.

You might want to check your mailbox to see if it is full or over quota, or is the recipient email is accepting mail at this time.

Hope it helps,
