For my mailserver I have a dovecot, postfix and sieve setup.
I have several hundred mails in my maildir and have recently created some sieve rules for sorting them. Unfortunatelly the sieve rules are by design only applied to incoming messages. Therefore my question:
How can I run sieve against messages in an already existing maildir?
With the link you provided I ended up using:
mkdir todo mkdir done mv cur/* todo for i in todo/*; do echo "Delivering message $i ..." /usr/lib/dovecot/deliver -d firstname.lastname@example.org < $i && mv $i done/ done
which works like I charm. I can rerun this script for every new filter I create.
