    Postfix - Odd emails creating too much traffic

    I was using Postfix without any problems but last two months time the traffic usage of the server is increased too much. When I checked the mail queue I see emails for an account which does not exist on my server. Below is an example how the mail queue looks like. I checked for open relay both manually and some online sites. There's no open relay.

    It causes too much traffic. And I see 60 to 700 messages in queue.

    messages in the queue are like:

    (delivery temporarily suspended: connect to mx1.likya. com[]:
    Connection timed out)

    Is this a kind of spam method? If yes, could anyone give me an idea how to fix it? Please help.

    Kindest Regards

    I found the problem. That was nothing to do with Postfix. It was a problem caused by a vulnerable Drupal script. I removed the script and the problem is solved.
