Hi, to change the order of mail_plugins helps to avoid following warning in logs and MAILER-DAEMON mails:

Command output: doveconf: Warning:
/etc/dovecot/dovecot.conf line 69: Global setting mail_plugins won't change
the setting inside an earlier filter at /etc/dovecot/dovecot.conf line 55
(if this is intentional, avoid this warning by moving the global setting
before /etc/dovecot/dovecot.conf line 55)
