This isn't enough. Darxus is using spamassassin as a pre-queue filter. Instead of "OK", use PREPEND to insert a header (or use a class that includes a check to PREPEND plus other checks). then have SA use this header (but make sure spammers can't insert the header themselves. so use a "secret" one...). note that you should do this for specific honey pot addresses or address patterns. do not do this for "any unlisted address" (people do typo addresses sometimes...). > [snip]
