Spam filter extensions

NethServer Version: 7.5.1804
Module: rspamd

Hey Everyone.

With the weaponized settingcontent-ms file doing the rounds I was wondering if I could block that extension in the email filter the problem being that it won’t allow me to enter that as an extension either due to it being to long or that it has a dash in it (the regex complaining about it)

Now yes I know that for the most part it will be delivered through a pdf or doc file etc. But I figured you never know when some n00b just tries to “default” an exploit.

That also being said. Is there a list of extensions that are blocked under the “executables” list? I like to have my bases covered.

@stephdl Could you help with this question?
