[Dovecot] maildrop index update

Hi,

I´m using a multi-storage architecture in my email environment and maildrop as deliver command at mta. But to this deliver the mx servers mount nfs partitions - we need to use maildrop because many patches we inserted.

How can I insert a piece of code at maildrop allowing it to update the dovecot indexes (which lib and/or function from dovecot I need to use ?)

Best Regards, Fernando
