Thanks very much for the very informative post. We also use postfix here. tallison@tacocat.net wrote: <snip>
I should note that there are a number of emails that are bounced as undeliverable from "real people" because of my UCE controls being so strict. Generally these are few and can easily be corrected by adding their address to the postfix access.db file.
How do you identify these situations? Is there anything short of grepping mail.log for rejects and then trying to guess which might be spam and which might be real? I understand that technically-savvy users will recognize the bounce and possibly reply to spam@<our-domain> (as we direct in our reject/bounce) but it seems to me quite possible that there will be some sizeable portion of users who don't have the inclination (or understanding) to go ahead and do that (as we direct in our reject/bounce). thanks very much in advance, ~c -- If you haven't got an agenda, chances are good that you're not doing much useful. --Stephen Frost
