Help! I tested getting gribauto files from my gmail account and it worked beautifully, but when I send the same requests from aviva@ocens.net my requests were rejected with this message:

<gribauto@zygrib.org>: host mx00.1and1.fr[212.227.15.41] said: 550-Requested
action not taken: mailbox unavailable 550 invalid DNS MX or A/AAAA resource
record (in reply to MAIL FROM command)

Below are the headers for the request sent -- is there something wrong here? Thanks for any help!
