Command:

sieve-filter -e -v -W ~/.dovecot.sieve INBOX expunge

Script:

# vim: set ft=sieve :

require ["date", "variables", "fileinto", "mailbox", "vnd.dovecot.pipe"];

if date :matches :originalzone "date" "day" "*" { set "day" "${1}"; }
if date :matches :originalzone "date" "month" "*" { set "month" "${1}"; }
if date :matches :originalzone "date" "year"  "*" { set "year"  "${1}"; }

if anyof (
		exists "List-id",
		address :matches :domain "from" "*plus.google.com",
		header :contains "Message-Id" "forum.ixbt.com",
		address :matches :domain "from" "*livejournal.com",
		address :matches :domain "from" "*youtube.com",
		address :is "to" "git-update-subscribers at altlinux.org"
	 ) {
	pipe "notmuch" [ "insert", "--folder=${year}/${month}/${day}", "--create-folder",
		"-new", "-inbox", "+unread", "+lists" ];
} else {
	pipe "notmuch" [ "insert", "--folder=${year}/${month}/${day}", "--create-folder",
		"-new", "+inbox", "+unread" ];
}
