    Can only receive emails from my self but when I send an e-mail out to [email protected] for example they receive the e-mail but when they reply back to me I do not get it and they receive a message saying:
    <[email protected]> remote host said: 550 5.1.1 <[email protected]> Receipent not found <>

    in the mail.log: I see somebody with an IP from China is trying to connect, what does it mean? did they hacked the server?

    Sorry false alarm,
    It was a name server setup mistake at the registrar.
    The sever works excellent, however I am worried about the strange IPs that tries to login from far.
