I apologize for the previous spam mail that slipped through. There's no need to complain to pathlink.com about it, since that is the Usenet gateway intentionally set up to gate the list with the newsgroup bit.listserv.openbsd-pf.
The problem was that the (proper) headers added by the gateway triggered a couple of spamassassin rules which shifted the balance towards a 'not spam' decision. I've now compensated scoring for gated submissions so they start with a neutral score. And they'll also be manually approved until the rules proof to work flawlessly. spamassassin has so far caught over 50 spam mails before they were sent to the list, and I'll do my best to keep it that way :) Daniel
