As I said: Read the man pages. >From the qmail-command man page: [...] EXIT CODES command's exit codes are interpreted as follows: 0 means that the delivery was successful; 99 means that the deliv ery was successful, but that qmail-local should ignore all further delivery instructions; [...] Doesn't "ignore all further delivery instructions" sound like something you need? :) $ cat .qmail-yourfilter |here-is-a-script-that-exits-99-if-the-sender-is-invalid &[EMAIL PROTECTED] > Also should i just check the From: field or is there anything else I > should check for (against the database, maybe using egrep) That entirely depends on what you want to do.
