    Have you contacted postmaster@freebsd.org? He should get in contact with
    SORBS and get the host delisted. My theory about how mx2 ended up there:
    Maybe somebody has an automated spam submitting system and SORBS parsed
    the addresses of one of the few spam messages that get through the list
    or either someone intentionally submitted a forged e-mail there.

    Either way, SORBS is a total joke and nobody should ever use them. They
    unilaterally blacklisted my /16 and there's zero change I'll ever get
    delisted until I pay the $50 "extortion fee". Apparently the facts that
    I've had the same IP for 5 years and that I publish SPF records don't
    matter.

    I laugh at the "Fighting spam by finding and listing Exploitable
    Servers." title in their web page. Google for 'sorbs sucks', nice reads
    :-)

    If you want to filter spam you can use spamassassin (disablig the sorbs
    and spews tests) and greylisting which works very well. SPF checks also
    catch a few forged e-mails on my server (probably virus-generated but
    spam nonetheless.)

    Cheers,
