[Rspamd-Users] Personalized File Blacklist

[Thomas Plant]

Hello,

wanted to ask if there is a possibility to create fileextension 
blacklists customized by domain or complete emailadress?
At the moment I am using a global blacklist for all users of my 
spamfilter configured in'force_actions.conf', but we have some customers 
who want receive .xlsm files for example (and possibly get hit by a 
cryptolocker).

Thanks for any hints how to accomplish this,
Thomas
