(apologies for top posting, but the email software here does not really do quoting in a way that works out well otherwise)
If your mail contains SpamAssassin headers then it was (obviously) processed through SpamAssassin. Just because you have BL checks in your MTA does not necessarily mean that all spam items will be blocked at that level. Lots of spam can pass some BL checks and then be scored high as the result of other things. My comments were not meant to say that BL checks stop spam. I was responding specifically to your inquiry about a rule being 'overlooked' if there happened to be a message it would hit that also had something in it that would hit a blacklist too. I think you're reading too much complexity into things. Or maybe not enough. The basic idea is something like this: a) You have some stuff specified for Postfix to do, it starts doing those things, and if it gets through them (without deciding to reject the message) to the point where you specify a call to SA, then it passes the item to SA for scoring. b) SA applies the rules (which usually include querying various blacklists based on things found within the message) and tallies up the score, then it gives the results to whatever asked it to analyze the message. c) Then whatever that was (in your case, Postfix) looks at the results and decides what to do next, based on what you specified for it. SpamAssassin does not block mail. SpamAssassin analyzes a message and assigns a score. Mail handlers reject/quarantine/discard/deliver mail. SpamAssassin is not a mail handler. If you don't understand the effects of entries in your Postfix configuration, you probably will get better assistance in a Postfix-specific forum. >>> Dan Schaefer <d...@performanceadmin.com> 07/23/09 10:22 AM >>> > It means that if you were using BL at MTA level your SA might never have seen > the message at all. > > No your rule would not be "overlooked" 'because the site is in a blacklist' > *unless* you were using the BL in your MTA and rejected the transaction from > a blacklisted IP address and, thus, never submitted it to SA at all. > > If this is the case, then why does my email have the X-* headers in it? I have nothing in my postfix header_checks to discard the BL rules. Does anyone have a detailed flow chart of SA/postfix setup and describes blacklisting? Or even a webpage describing the process?
