With v1.0 it would be pretty easy, but v1.1 makes this more difficult because it doesn't keep dovecot.index up-to-date all the time. Instead you'd have to read dovecot.index and apply new changes from dovecot.index.log.
- how would you proceed, if the aim is to end up with dovecot notifying a database regarding the number of messages, and unread messages?
Create a plugin which overrides mail_storage.sync_deinit(). Quota plugin could be used as an example:
static int quota_mailbox_sync_deinit(struct mailbox_sync_context *ctx, enum mailbox_status_items status_items, struct mailbox_status *status_r) { struct quota_mailbox *qbox = QUOTA_CONTEXT(ctx->box);
/* just in case sync_notify() wasn't called with uid=0 */
quota_mailbox_sync_finish(qbox);
return qbox->module_ctx.super.sync_deinit(ctx, status_items, status_r);}
Call super.sync_deinit() with status_items having STATUS_UNREAD. status_r->unseen then contains the unseen counter.
If you want to avoid useless database updates, you could call mailbox_get_status() in sync_init() and save the unseen count there, and then compare in sync_deinit() if it got changed.
