The first thing you could try is enabling Greylisting. It will decrease the spam amount to a significant degree. https://www.howtoforge.com/greylisting_postfix_postgrey The second thing is to add Spam Black-/Blocklists to your configuration: https://www.howtoforge.com/block_spam_at_mta_level_postfix Third thing is to manually train your server via sa-learn and then set the spamfilter levels accordingly.
