Hi all Im using
FEATURE(dnsbl,`spam.dnsrbl.net')dnl and also have published an spf record and are rejecting based on spf records. I notice Im still recieving mail from domains where the domain does resove but the MX records for the domain dont. Is there are way to reject these. Other good sendmail based anti-spam techniques? note: we have "smart" antispam filter further inside the network. The above is just for a border sendmail installation where I want reject as much spam based on unresolvable hosts and user named as much as possible. thanks BB -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
