I use amavis, spamassassin, postgrey, and my own procmail monster. People say good things about rspamd. I also use OpenDKIM and OpenDMARC, but only to add headers. Postscreen in Postfix probably does everything that postgrey does and more. RBLs are also a thing but some of them can block a lot of solicited commercial email as well as unsolicited commercial email. Sorry if you already knew all that, and only wanted information about commercial software. cheers, raf
