dovecot - Apr 2006 - How to notify dovecot that maildir contents is changed by third-party helper ?

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

#  * When mailbox contains "Spam" subfolder,
#    all remaining spam messages are moved to this subfolder.

There shouldn't be a need to do anything.

Only dovecot.index and dovecot.index.log should be changed, others might
not.

Hmm. What happens if you do "touch cur" after deleting the mails, are
the mails noticed then?

Alpha5 is somewhat old too, so it's possible that it has some bug
related to this. I'd suggest trying newest beta.
