I search the best way to move spam mail to a folder readable by users. On other server.. i have email email@example.com and alll spam are go on it. But i don't know how i can install it with ispconfig and postfix I use SquirelMail, because it's on installation by default. I use the Centos OS. On other server i use roundcube. It's possible to easy add pluggin in squirelmail ? Because i dont want scrap ispconfig.
