Answer 1

adicione as configurações abaixo ao arquivo /etc/dovecot/dovecot.confe recarregue o serviço dovecot.

service stats {
  unix_listener stats-reader {
    group = mail
    mode = 0666
  }
  unix_listener stats-writer {
    group = mail
    mode = 0666
  }
}
service anvil {
  unix_listener anvil {
    group = mail
    mode = 0666
  }
}
