Backup MX and greylisting
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) ŕ 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 ?
