Unfortunately, your mail was not delivered to the following address:

nuwt@netzero.net:
127.0.0.1 does not like recipient.
Remote host said: 554 nuwt@netzero.net Mail quota exceeded
Giving up on 127.0.0.1.

Hi,

it just means that the mailbox of
nuwt@netzero.net is full and won’t accept further mails until the user cleans up his mailbox
either wait or contact the user some other way :wink:
