Hello, I did follow https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/ and everything works absolutely fine. Thank you for the documentation (very much appreciated). I have a question with regards to quarantine. Is it possible to quarantine e-mails instead of rejecting these? I am running ISPConfig 3.1.15p2 on Debian Buster 10.1 with Apache 2.4.38. Thank you.
rspamd uses milter to sort mails. -> rspamd only suggests, what should happen with mails, milter is performing the action. Since version 1.9, rspamd can use the option "quarantine", which is interpreted in postfix as "hold". So, yes technically it is possible to quarantine instead of reject mails by using the option "quarantine_on_reject" in rspamd config. However, I have never tried it and don't know, how one would proceed with quarantined mails. For milter, see: http://www.postfix.org/MILTER_README.html#errors For rspamd: https://rspamd.com/doc/quickstart.html (search for quarantine)
