[Dovecot] Is it possible to regenerate the index files?

Is it possible to regenerate the index files, on other conditions than the mbox file being read?

For instance, it would be nice if I could regenerate the index for a specific mbox whenever procmail delivers mail to it.

If theres no existing solution, would it be possible to make a small script with something like "nc" that could send an imap command to dovecot, so that dovecot would rebuild its index for that mbox? If so, which imap command triggers an index rebuild?
