I exchanged some more messages with tech support and got more info on Gmail spam system:
Thanks for your patience while we investigated this issue. The best solution for your needs will be that we add the last hop IPs before the messages hit the Gmail gateway to an internal whitelist, it might be just one IP or multiple IPs depending on how you have set up your gateway. This IP list will actually facilitate spam classification by the sophisticated Gmail spam classification service that processes hundreds of signals,not only connection IP, for positive identification of spam. You can read more about this in a public white paper published by Google at http://www.ceas.cc/2006/19.pdf. We will be happy to do this as soon as you provide us the IP addresses. Without adding your gateway server to a whitelist, it is possible that your gateway server is penalized for forwarding spam to users through Gmail. Another suggestion I have is that you make sure that you are not forwarding large amounts of emails to users unknown to Gmail i.e. users that exist on your domain but aren't yet created in your Google Apps account. Admins who are testing Google Apps for large organizations tend to do this and they set the routing settings to route all unknown emails to their internal servers. This works as expected but the domain reputation may suffer when Gmail starts getting too many emails for users unknown to the system. They've since added our gateway IPs to their internal whitelist and we have begun the rollout to our students. The system won't be available to everyone until 2/25, but I've opened it up to a test group of a couple thousand, so I should start getting reports soon if there's a problem. -Eric On 2/5/08, Alex (Google) <[EMAIL PROTECTED]> wrote: > > > Hi Eric, > > This is a good question that I don't know the answer to.
