What we did was to isolate our forwarding traffic out through a separate set of IPs. And then told Hotmail, Yahoo, AOL etc about the IPs. They were very glad to tag these as such in their filters This was over three years ago, and admittedly, our email traffic is rather higher (by orders of magnitude) than most but it is still a good idea to isolate forwarding traffic and separate it from regular outbound email. Another advantage - monitor the mail queue of your forwarding IP and it gives you a very nice little snapshot of what kind of spam is slipping through your filters srs On Fri, Apr 4, 2008 at 2:22 AM, Raymond L.

yeah, We do hosting for about 300,000 users in our shared environment. They have forwarders setup or aliases that send to their external addresses. This forwards their spam as well. We purchased quite a few barracuda servers and became their case study for outbound units. They actually do a really good job at blocking the spam. But as spam changes every minute, we can only get updates every hour. The mail forwarders is the only spam that come from our network. Try subscribing to hotmails reporting services so you get reports on spam from your IP address, and they have the online reports that show if you add your AS so you can see a report for all ip's in your network. -Ray
