    I'm sorry but since I install Postfix (a lot of years) it's the first
    time I have this problem, (blacklisted in Backscatter.org, SORBS-SPAM)
    and I would like to know why !

    Actually the server is a mail relay for a Zimbra server (www.zimbra.com)
    on two Vservers on the same host. I don't find any explanation on why
    our IP is listed on Backscatter.org, on the website the request page
    notify this note:

    -------------------------------------------
    This IP is temporary listed.
    The listing will expire automatically and free of charge 4 weeks after
    the last abuse is seen from that IP.
    Expedited manual express delisting is available as an option, in case
    you do not want to wait for the automatic and free expiration.
    You will be charged 50 Euro's using one of the following payment services.
    -------------------------------------------

    It's not an ABUSE !!!

    But what should be the origin of the problem and what is the quick fix ?

    Thanks in advance.

    Sam.
