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
