Funny, I just asked about doing this within the last week in a thread "postscreen and Google" The answer, direct from Wietse, is > Don't enable the "after 220" tests, or wait until whitelisting is stable. > Given that Google has many servers, manual whitelisting is not a long-term > solution. If you're server is high-volume, you need to run post screen for a while with soft-bounce enabled to build up the cache. A month. You might also read the thread "Snapshot 20130517" which details up-coming changes in 2.11 that will allow whitelisting via a DNS RBL-style lookup. (I went with disabling the after-220 tests and postscreen is still doing an excellent job of keeping mail from having to go through spamd, significantly dropping my server's processor load). -- Can I tell you the truth? I mean this isn't like TV news, is it?
