i am using mailscanner. i have enabled storing spam & non spam emails by adding “store” in spam action config. its storing the emails in quarantine folder, but in mailwatch panel, quarantine action not showing, also in release its showing: Message not found in quarantine.

if its just a 1 click install any reason why no emails are showing
fresh install of Cyberpanel all up to date
Email working no issues, and Spammassion working fine and RSPAMD working no issues

i have the same issues.
i also found out that mailscanner needs to have mariadb devel and a module otherwise the tab recent messages won’t work. these are the commands:
dnf install mariadb-connector-c-devel
cpan DBD::MariaDB
systemctl restart mailscanner

i’m trying to look an easy way to filter spam (instead of sieve) but this gives me another headache…
In software version i have:
Postfix Version: postconf not found
and spamassasin version is completely missing (even though mailscanner can’t be installed without spamassassin)

and still don’t know how to filter spam and put it in quarantine…
