[Dovecot] Virtual mailboxes not always up to date?

[Patrick Nagel]

Hi,

I have been experimenting with the Virtual mailboxes plugin [1] recently.

This is my setup: the following dovecot-virtual file exists in a virtual
mailbox called "todo":

------ dovecot-virtual ------
*
-Trash
-Trash/*
-Spam
-Spam/*
  OR KEYWORD $TODO KEYWORD todo
-----------------------------

so if any mail in any mailbox except Trash+Spam has the keyword "$TODO"
(that's what KMail sets when you mark a message as "action item") or "todo"
(that's what Thunderbird sets when you put the Todo tag on a message), it
should be shown in that 'todo' virtual mailbox.

This works for the first time after I edit the dovecot-virtual file and
then access the virtual mailbox (all mails I expect to be shown in the todo
mailbox are there) - but further accesses always show the same content,
even though I removed the keyword from one of the mails (and I can confirm
that the keyword has actually been removed by dovecot, since the filename
doesn't contain the letter corresponding to the keyword anymore).

It seems that changing the dovecot-virtual file triggers the execution of
the "search program" - but shouldn't simply accessing the virtual mailbox
also trigger it? Or is there a (undocumented?) timeout between search
program executions?

Patrick.
