    when i am sending mail it giving error

    The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[email protected]'.

    This simply means that the account does not exist on the remote server. This has nothing to do with your server.

    My office user connected with my server. But some another city user connect directly connect remote server where i web host with same domain. When my site user send another city user mail then give error.

    if i remove /etc/mail/local-host-names then mail easy going out site.
    but every one mails office user and another city user directly going with smart host and local user mail not drop in locally.

    Mdaemon server have this feature with unknown user easy go out side with smart host and local mail drop local mail box.

    Ok, this means you have configured the remote domain on the local server, that's why emails don't go out. Either remove the domains from /etc/mail/local-host-names, or configure a transport. For Postfix, that a look at
    man 5 transport

    You probably need a special Mx record since mail on the same domain may be considered delivered.
