Copy the generated files from the step №3 from
/root/.spamassassin/to the.spamassassinfolder of the required mailbox, for the example [email protected]:# cp /root/.spamassassin/* /var/qmail/mailnames/example.com/johndoe/.spamassassin/
Set the correct ownership for the copied files by executing the command below:
# chown -R popuser:popuser /var/qmail/mailnames/example.com/johndoe/.spamassassin/*
Note: after the steps above the antispam database will be applied to [email protected] mailbox.
