Dear, i have problem with email. Someone maybe hack me email, and send very much email from my domain (email: [email protected]), but i dont register this email at the ispconfig. How can I block this email adress and block this user. Thank for help
That's the website mail. You must check your website because surelly it has been hacked. If you are using WordPress or another CMS update it. Meanwhile, you can disable php mail from your site going to sites tab, select the problematic site, options tab and write this under custom php settings: disable_functions = mail
