thank you so much, actually I did behave such a big stupid, I copied the main.cf from german server and , wait to work mine , how can it be,of course it didnt work, there are a lot of services , smtp, canonical, taransport...
but I didnt have anyone of them,
as you said, I start to beginnig, from simple to complex, why I didnt this at the begening, actually I was so nervious , I just started the work and they want me to do, big stuff, I thought like that bt know I start to like linux, it is so lovely than xp , because, I feel I am a user, because I should do something not click yes and yes,
I should say:thank you so much all,
of course I have questions more, but I am afraid to ask, because when I read my previous posts, I thought what a idiot I was at the time I was posting
anyway again thank you ,
see you soon, for example tomorrow
bye
