# Comando (pkgs.dovecot_pigeonhole) para filtrar mensajes existentes:
#
# $ sieve-filter -v -C -u alejandro@34project.org ~/.dovecot.sieve INBOX
#
# Ese comando es un dry-run, agregar "-W -e" para proceder. Probablemente es
# buena idea hacer 'snapshot -r' de ~/mail antes de ejecutar eso. El primer run
# tomó como 15 minutos para procesar todo el maildir.
