I have 10 years of sending emails, (because I have e-card sites), and due to the volume I get a lot of incoming spam. I would like to suggest to you that you are not going to stop all spam, 100% all the time, no matter what you do. And Though I understand your desire to to accept all the emails at your server, that leaves you with a bit of a backwards conundrum.
I think you would do well to pay attention to this... At one level you could be playing with fire by forwarding all these emails. Each ISP has their own filter systems in place, and some of them integrate services such as SpamHaus or Spamcop. *I have seen emails rejected because of blacklisted IP addresses and/or blacklisted domain names in the emails. So if you forward emails that contain blacklisted IP's or domains you are likely to run into some difficulty.* For that reason alone I would personally attempt to block more known incoming spam using DNSBL's, especially using the two I have just mentioned. Amongst others, I personally use: reject_rbl_client sbl.spamhaus.org, reject_rbl_client xbl.spamhaus.org, reject_rbl_client bl.spamcop.net If emails are rejected by the clients above, it's generally going to be for a good reason, though not 100% foolproof, it's a pretty safe bet to use them, and certainly more accurate than spam filters. In doing so, you will knock down wasted emails, system resources, and time. But you may also help prevent yourself from getting RED flagged for having blacklisted IP's and domain names in your outgoing emails. Beyond that, shy of manually approving all the other incoming emails before forwarding, I would suggest that you consider other options. *AOL has a "approved senders list" for it's users*, the users input what email addresses they will accept email from, "whitelisting", and the rest is rejected. You could do something similiar, even if you simply trash the emails that are not on the whitelists. You probably could set it up so that any email address in any users contact list simply be added to the whitelisting. ----- Free English & Spanish Ecards for Birthdays, Christmas , holidays, Valentines , Love , & just because! -- View this message in context: http://postfix.1071664.n5.nabble.com/Do-not-forward-spam-tp61620p61794.html Sent from the Postfix Users mailing list archive at Nabble.com.
