    The problem here is that the MX record for your domain (i.e. the sender domain) is set to a private IP address. Often the receiving mailserver checks the sender domain to be sure that the source of a mail is valid. My sendmail server does this.

    If you make sure that your reply address domain points to your real email domain, you shouldn't have any problems.

    Yes, I have an mail server, and behind him, desktop computers with private ip addresses.
    Do I change MX record? How can I do that?
    How to verify that my reply address domain points to my real email domain?
    Thanks a lot for your suport.

    It's normally enough to make sure that the IP address through which you connect to the internet points to the same domain as the 'return address' in your email. You set the 'return address' in your email application (evolution, kmail, thunderbird, or whatever).

    I do it that (with the mail client), and it is the same problem.
    I guess the solution is to set MX record to public addresses.
    How to do that?
