According to the Wiki

"It is not wise to place this link inside your mail store, as it may be
mistaken for a mail folder. Inside a maildir for instance, the default
.dovecot.sieve would show up as phantom folder */dovecot/sieve* in your
IMAP tree."

Sorry i am a bit of a noob, the docs don't explain clearly what to do...
