I can't use smtp and pop3 servers from other cumputers of my network. I made changes in hosts.allow (ALL: 192.168.0), I had created an user with password and smtp works in local. I can see knoppix open ports from others computers but I can't talk to them and login ! I'm a novice and I 'm doing something wrong but what ?
