Permanently reject emails based on custom (blacklist) patterns?

Permanently reject emails based on custom (blacklist) patterns?

My Spam control SPF verification settings are set to "Move to Quarantine" because I would like to catch the emails that are not really spam to be still deliver by hand. 

However, I notice that a lot (and I mean really really a lot) of spam emails are being quarantined because of the spf rules (fail and soft fail) and most of those spam emails have a similar pattern: 
- a subject that contains certain words like 'can we meet' or 'hungry for you' and other crap..
- no text in the email body, but only a (base64 encoded) image containing an ad. 
- domainnames that are from some obscure tld like .ar or .icu or .pk and so on....
- specific ip ranges
- mails from certain regions (I do not know any companies from nigeria, just put it on blacklist)

I would really like to be able to permanantly reject emails that follow such a pattern. 
The most perfect way would be to set some 'permanently reject' rules that can be customized.

That way, with a bit of setup rules, I am sure that I can permanently reject a lot of emails without losing the ability to manually detect the 'false positives' spam-emails in the quarantine.
