Make sure that serve1.sisdistribuidos.com is pointing to the right IP address. You can check that with Code: dig serve1.sisdistribuidos.com

There's no ANSWER section which means that no DNS records exists for server1.sisdistribuidos.com. Please create one.
Falko sorry but I'm not expert in this topic I check in /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 192.168.0.100 server1.sisdistribuidos.com server1 ::1 localhost6.localdomain6 localhost6 I think i don't need dns because i only need to send email into lan, in this moment the dns is my isp,so i need that the client recongnize the name server to try configurate accounts in thunderbird or something like that. Where I should add the records for server1.sisdistribuidos.com? can u help me o lot of more please? and excuse me again for my ignorance. Thx
Your client PCs don't know the IP address of server1.sisdistribuidos.com. You must add it to their hosts files as well: http://www.howtoforge.com/forums/showthread.php?t=432&highlight=hosts+file+windows
Falko I did it and it is working now,thx a lot, you are simply the best I have a last question. Can I configurate the mail server with dynamic ip? if it is do you have a link with this information? B.R
If you use a dynamic IP, the server will most likely be blacklisted. As a workaround, you can relay through another mail server: http://www.howtoforge.com/postfix_relaying_through_another_mailserver
