    Hello,
    I have a huge problem with a unknown site there is sending out spam, probably hacked... :(
    Is there a way I can track the activity, to determine what site it is coming from?
    Another thing, can I somehow permanently ban Fail2ban bans, as you can see I have a lot. I found a tutorial online but as I can figure out if it's only for brute force attacks...

    Code:

    Check your web logs for requests that keep recurring, and also check the contents of some of the messages for clues (you'll likely find some in your mail queue, just use postcat on the files to dump their contents, and see what you find).

    I didn't know that, thank you very much.
    I will give it a try right away.
