I have set up rules in the Rules config section to do the following:
1. smart block of all exe files (also included *.scr)
2. dangerous executables to block among other extensions *.scr
on of my users got an email with a zip file. inside the zip was another zip and inside it a filename with scr extension.
How did the scr file passed both rules and got to my user mailbox? Doesn't the Rules config search inside attached archives for blocked files?
