    Hi all,

    i experience some problems with qmail.
    Someone found a hole in my server (suse 9.3) and sends thousands of spams...
    Does anyone has a script in order to find out where is the problem? (web form? other vulnerability?).
    At mail-wide preferences on my server at WHITE-LIST the value is: 127.0.0.0/8
    Is this safe? After some search about it, i found out that the correct value there is: 127.0.0.1/32 .... Which one is correct?
    I have a lot of different domains/clients on my server, and all of them have web forms and i tried to check all of them, and patch them with "eregi" for avoiding injections). Is this correct?
    Does anyone has written a script that runs allways on the server and checks for non-logic email sends?
    Is there any configuration for qmail to LIMIT the recipients of a mail?

    Thank you.

    Zeroborg.

    The quote below is the body of a previous post that I saved just in case I needed it. Sounds like it may be what you are looking for. depending on how many domains you have on your server, it may take a while but it is better than not doing anything. I have not tried it myself so I do not know if it works. You may want to test on a known script before you do all of your domains just to see if it works:

    I have a problem where a client has a redirect email ends up in the message queue and stays. It is never delivered. So I have been searching for a solution. As I was searching for the solution, I came upon your post talking about the White List indicating the IP of 127.0.0.0 / 8. As I read through the post you said you found the correct address. Can you tell me where you found this information?

    I am new to using Plesk and have had problems galore, but if I can find where the information is maybe I can solve at least one problem and maybe more.

    Thank you in advance should you reply to my post.
