+1. rspamd doesn't do badly even with little/no training for spam/ham. It does have problems with certain mail, for example it likes to have various MIME headers, so you may need to make some exemptions for things like daily/security mail output, or mail from people who don't use MIME MUAs. > 2.

Definitely you would need to read documentation if using tools like rspamd or spamassassin.
