    Can you post the errors from your mail log here directly (instead of attaching a file)?

    Hello

    the command telnet is now working in the client, but i don have idea what was the problem,but telnet 192.168.0.100 25 is working.

    Friend i need you help again,i need to configurate a client like thunderbird outlook or something like that but i dont have idea.I have some problems

    1-the ip server is 192.168.0.100
    2-the localdomain is sisdistribuidos.com(is not real)
    3-the name server is:server1.sisdistribuidos.com

    when i do pin to 192.168.0.100 it replies correctly
    when i do pin to serve1.sisdistribuidos.com it does not reply(maby dns,i don't know)

    1- I need to configurate a client like thunderbird or outlook
    2- I need to configurate the webmail
    This should work in a lan because i dont have a real domain.

    I estimate you help

    Best Regards:)

    you should check the listening ip address of your mail server:)

    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.

    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?:confused:
    can u help me o lot of more please?
    and excuse me again for my ignorance.:confused::confused:
    Thx
