Move E-Mails to subfolder of inbox using sieve

Question

Do I need any option, to move matching emails to a subfolder of the inbox?

My /etc/dovecot/conf.d/10-mail.conf:

    namespace inbox {
      inbox = yes
    }

And the /srv/vmail/spam-global.sieve:

    if address "From" "monitoring@example.com" {
            fileinto "INBOX.Monitoring";
    }

This configuration is currently creating a new main folder "INBOX.Monitoring" instead of an INBOX subfolder "Monitoring".

Answer 1

Try / as parent-child separator: "INBOX/Monitoring"
