For some DNSBLs, yes. For others, you want to allow SpamAssassin to score them. As long as you are bypassing DNSBL checks for authenticated clients, you can safely block everything at SMTP session level with ZEN. In turn, I disable the Spamhaus ZEN checks in SA, as there's no point in querying ZEN twice when everything that shows up there is bloked before it gets to SA.

I personally do not block on bl.spamcop.net, but it does add a score of 2.0 in SA. -- Best regards, Robert Braver rbra...@ohww.norman.ok.us
