Hi, folks! How to notify dovecot that maildir contents is changed by third-party helper?

My script performs spam cleanup, but all index/cache files (dovecot-uidlist, dovecot.index, dovecot.index.cache and dovecot.index.log) still unchanged, so, Web-frontend (IlohaMail over IMAP) displays taht mailbox contents isn't refreshed.

Dovecot 1.0-alpha5 under FreeBSD 4.11. mail = maildir:/var/vmail/default/%1n/%n

WBR, Ilya

#!/bin/bash

CleanupMailboxSpam

Tracks mail directories of Dovecot IMAP server

and moves/removes all messages marked as spam by SpamAssassin:

* When mailbox contains "KillSpam.<number>" subfolder,

all spam messages with score >= <number> are removed.

* When mailbox contains "Spam" subfolder,

all remaining spam messages are moved to this subfolder.

* When mailbox contains "KillSpam" subfolder,

all remaining spam messages are removed.

TODO: update indexes and caches on altered mail folders!!!

Only for testing: doit=echo; export doit; ...

This prints all modification commands instead of executing them.
