Hi, I'm french, sorry for my bad english. I setup 2 potsfix server : - the first (server1) is a full serveur : postfix/amavis/mysql/postgrey, etc... - the second (server2) à backup mx without postgrey, amavis, etc... With your very good tutorials ! In DNS 2 MX : with 10 and 30 Two works perfectly ! On normal opération server1 AND server2 receipt email. server2 forward to server1 In the case where the mail transit through the server2 -> server1, the postgrey list of server1 is always effective ? Or is the server2 waiting for x minutes and forward again ? Jerome
You can put server2 in the postgrey whitelist. See http://www.debuntu.org/postfix-and-postgrey-a-proactive-approach-to-spam-filtering-p2
Thanks, But I think that it's not the problem. The problem is that the bakcup MX relay become the sender to the server1. And Postgrey is bypassing. So, i will install postgrey on the server2. It's not a beautiful solution but it works. Any other ideas ?
