How do you set up > your filters? 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.)
