Package descriptions

[Claude Reveret <claude.reveret-spam@free.fr>]

Hello,

I want to translate a package descriptions, but each time I send a mail to   
desc@ddtp.debian.org with the subjet get 1 fr I have the answer :

This message was created automatically by mail delivery software (Exim).

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  desc@ddtp.debian.org
    retry time not reached for any host after a long failure period

How can I translate a description of a package ?

Best regards, Claude
