Incoming mails will be forwarded to sieve after creation of

FILE ~/.forward~/.forward for Sieve usage
| "/usr/libexec/dovecot/deliver"

Define the filter rules in

FILE ~/.dovecot.sieve~/.dovecot.sieve example file usage
require ["fileinto", "envelope", "imap4flags", "mailbox"];
# mailbox is required to create folders if they do not exist
# refresh the folder list in your IMAP client and subscribe new folders

# Spam filter
# X-Spam-Score: 5.
# X-Spam-Level: *****
if exists "X-Spam-Flag" {
  if header :contains "X-Spam-Level" "*****" {
    fileinto :create "spam";
    addflag "\\seen";

# bugs
if envelope :is "from" "" {
  fileinto :create "INBOX.bugs";

# test
if header :is "subject" "test" {
  fileinto :create "INBOX.test";

# commits
elsif header :contains "List-Id" "" {
#addflag "\\Seen";
  fileinto :create "INBOX.list.g-commits";
# core ML
elsif header :contains "List-Id" "" {
  fileinto :create "INBOX.list.g-core";

# announce ML
elsif header :contains "List-Id" "" {
  fileinto :create "INBOX.list.g-dev-announce";

# catchall ML
elsif header :contains "List-Id" "" {
  fileinto :create "INBOX.list.gentoo";

Test your configuration by sending a mail with the subject "test" to yourself and monitor ~/.dovecot.sieve.log

The subfolder INBOX.test will be created automatically, but you may have to subscribe it in your mail client.
