In the meantime, I found it should be placed in the user_prefs file of 
SA in amavis user filetree.

I placed it and I have already seen  spam being blocked with it!

So thank you Matus! Any improvements/additions will be welcome!

Would there be a way to identify spam by noticing that Sender has a 
known name but an inconsistent mail address (because it is modified by 
spammers), as I have earlier described?
