    Hello,

    It was strange yesterday suddenly all email accounts on my server stopped working, when sending or receiving emails, there would always be an error like: no such user.

    I thought it was the RDNS problem at tje begining, but seems it was not, because today when I was terminating one existed user account on this server from WHM, it showed this error:

    Then I terminated another testing user which was created a few days ago, the same error appeared.

    Whenever that warning message appeared, the user account removed from the account list in WHM, however that was very strange.

    I then tried to create a new testing user, and attempted to terminate it, to see if the same error would appear again or not. No, no similar message appeared when terminating newer created user accounts, but for terminating ALL "OLD" accounts I saw that strange error.

    Why that happens? I did not do anything to my server, why it says all these users do not exist? Can anyone help?

    This is a new server, with the latest version of CPanel/WHM. Waiting for help.. URGENT....

    THANKKKKKKKK YOU!!

    TT

    So, a small update:

    I recreated an account, which had email problem.

    I have just tested to send/receive email using that account, no problem any more.

    A very serious concern has just come into my head, WHY accounts on my server suddenly become non-existent?? They exist though, they can login their cpanel, upload their webpages, just they are "no such user" to email servers, and "does not exist" when terminating from WHM!

    No other error logs, no hacking records..

    Wish to hear an answer to this!
    Thanks!

    I suggest you seek help from your Data Center, or get professional help. In your case, it is really difficult to say without looking into your server.

    I think you are right, now something more interesting: when I visit the main shared IP of that server via web browser, it opens the homepage of one of site which used to be using that shared IP...

    OMG... >.<
