I doing a fresh install of ispconfig into Debian 10. I would like to use rspamd and not spamassassin. Currently I am following the following documentation. https://www.howtoforge.com/perfect-server-debian-10-nginx-bind-dovecot-ispconfig-3.1/ It does not mention rspamd. Is there another documentation with rspamd instead of spamassassin? Or is spamassasin a dependence for ispconfig?
No. Follow the perfect server guide and then replace spamassassin with rspamy by using this guide: https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/
