    I have made an email-address in isp-config latest update made.
    I can send email but not receive email, the sender gets "unknown user".
    Mail from other Domains on the same server work normal.

    Where do i start looking for the problem, in the postfix logfiles i cannot find anything.
    Gratefull for any hint.

    seems my mistake, needed to change the hostname to "server.mydomain.tld" instead of "mydomain.tld"
    just renamed it, now see what happens.
    problem solved

    The most likely reason is that you used that domain in postfix file or as server hostname. The hostname must be a subdomain and the domain may not be listed in myhostname or mydomain in postfix
