Hello, I have the last ispconfig 184.108.40.206 installed on ubuntu 10.04LTS updated. One of my customer with an old joomla site was hacked. Few hours after, a lot of spam are sent from his site. This is the fact. All spam come from [email protected]e. Now i have stopped the site, clean the postfix queue from all spam mail and now i try to understand if my server is secure and if I do other actions for secure it. Because is not possible for me control every site and every plugin of my customers, my question is: Is possible disable send mail from the user [email protected]e or is necessary for correct ispconfig functions, and how; there is a secure configuration that is possible apply for the sites with CMS installed or php function to disable for push-up the security ? thx in adv.
