Hello,

I am trying to automate anti-spam flood on our Plesk servers, and my goal is to be able to REJECT mails from abused mailboxes or from non-captcha'd web
forms.

On the mailboxes, the directive check_sender_access works as expected, no
problem here.

Whenever I try to REJECT mails from root@localhost (sendmail -t <recipient>, for example), or from a web form that uses a local UNIX account, it does not
work. Just goes straight out.

Anybody knows how to do the trick?

Run 'man 5 postconf' and look for the section on the 'authorized_submit_users' directive.
