Dear list users, I use a postfix MTA as a mail gateway for sending mail only (no mail is received by this server). If I tell postfix to listen on internal lan eth (10.0.0.2) only it cannot tcp-sync to other MTAs on inet eth (192.168.1.100). If I tell postfix to listen on all eths tcp-sync to other MTAs port 25 is no problem. Why can't I close port 25 on inet eth (192.168.1.100)? What did I miss? thanx in advance, philipp
